| How can I identify source of interference on 5Ghz? Posted: 14 May 2019 04:21 PM PDT HI, I installed a new 3 tower velour system, it's been about 2 month and has been awesome... At my kitchen, which has a tower 10 feet from me, it negotiates on 5Ghz for 7 Mbps... and it's not only on 1 device. 2 Macs and 1 Windows... on the Windows machine and on 1 Mac i forced on a 2.4Ghz channel and I get 190Mbps. When not forced, goes to a 5 Ghz, and down to 7-13Mbps.... So I assume something is creating major interference on 5 Ghz... how can I "scan" or search for the source of interference? Thank you for your time! [link] [comments]  |
| Need help choosing cheapo UPS for my network stuff Posted: 14 May 2019 09:44 AM PDT Here are my babies whom I need to protect from the angry gods of fluctuating electricity. They are
My budget is quite limited, so any true sine wave online units will probably be too expensive. I'm also not in the US, so the normal brands of Cyber Power, APC or Eaton are prohibitively expensive; instead, there are some local brands that I'm looking at. I have access to refurbed units with brand new batteries from a reputable local distributor. My current top choice has the following specs:
My questions are as follow:

| Advice for cabling for new house build Posted: 14 May 2019 05:41 AM PDT Hi everyone, moving into a new house build in the new year. Can anyone help advise me on a few items regarding the cabling / wiring for the home network? I'm fortunate in that I have the opportunity to decide what to chose, but having to lock in on these decisions is proving tricky, I'm conscious of making a wrong-decision that will be hard to reverse. Would appreciate any inputs people can share. Thank you House Layout: House will be 2 stories, 8.5 meters from ground to top of side gable. 9.5 meters from front to back outer walls 9.5 meters from East Wall to North outer walls ISP enters house on ground floor, in living room on east side. ISP router will be left here, used as WiFi AP for that room / dining room / kitchen. Router will be left there so device can be rebooted easily if needed. Electrician will route a cable from here up to attic. Here I will have a Switch which will be fed by the router, and cabling from all other rooms will run from. 2 CatX jacks / ports in TV room on West side. Will have a Smart TV, Xbox, PS, Steam Link (if TV doesn't have included) - who knows what else! Every other room will have 1 jack / port and a coax cable. - Questions: Ports / Panel Types: Does the CAT cable type used in wiring the house have an impact on the Switch model required? Would a patch panel be useful to have the wires from each room coming into the patch panel, labeled, and then connected to the Switch? Is there considerations for the type of jack required when deciding the CAT type to use? Cable Type: What Cat6 type to use? Cat6 or Cat6a? The electrician we have mentions he has Cat6, he's not sure on which type he has. If it's Cat6 and not Cat6a, is it worth pushing him to get Cat6a? Conduit: Is a Conduit to chase the cables overkill? How much cost does it add, typically? Are there other ways to replace cabling in the future? A buddy mentioned that cables can be installed with a string that can be used to pull the cables back etc. Cabling for Satellite: What to ask for when cabling for satellite? Dish would be on East side of the house, how does wiring for TVs in 2 locations work? Coax is included as standard, but there is a double coax type of cabling specific to Satellites also, if I'm not wrong? I'd like to cable for the satellite into both east side living room, and west side TV room. WiFi / APs: Regarding Wifi, as I understand it, the house is quite well insulated, very high energy rating. It's a concrete / block home. I plan to use CatX ports that are present in every room to attach APs to get a good spread of coverage. Is there a method / approach to this? HDMI: Are there considerations/recommendations for HDMI wiring similar to how CatX and Coax is being done? Is it a thing people do? If so, why? Attic: What kind of concerns / considerations would there be for leaving NAS and Switch devices etc in an attic space? Should I be looking at buying / using some type of rack or cabinet? What about dust / heat? [link] [comments]  |
| Posted: 14 May 2019 08:24 PM PDT Hi, My place has some WiFi deadzones in the room farthest from the router. My girlfriend wants us to get a WiFi extender, which I'm fine with. However the one she is suggesting is one she found on amazon called by a company called Rock Space (product is Rock Space Range Extender). I'm pretty wary about these weird Chinese brands on amazon, does anyone know anything about this project/company? [link] [comments]  |
| New home New physical topology question Posted: 14 May 2019 07:59 PM PDT I am trying to decide what method to use for complete coverage in my new home. It is significantly bigger than my current one so i know my current wifi ap setup wont cover it as my current house is barely covered already. Presently I am running a Nighthawk R8500 with DD-WRT, small weak signal spot in my house due to hvac placement but otherwise fantastic signal even out in my drive way/backyard with mild power settings from its central placement. I have been deploying Ubiquiti Gear at my place of employment and love the hardware. We have a dozen or so of their APs and I setup the unifi controller suite on a debian9 VM with basic wifi access. Havent had time to dig into the capabilities of said system for tweaking things. Question is, am I better off purchasing another R8500 and running DD-WRT on it for the sheer amount of fine tuning this allows me from signal power to security control OR does the Unifi suite give me the same kinda of fine grain power in one sweet little place? the other nice thing about the R8500 is that I can use it as a switch as well to mitigate the amount of home-run cable pulls required.

| Posted: 14 May 2019 01:35 PM PDT Hi I just recently moved to a two bedroom apartment and am in need of a new router. There is usually only two people using the WIFI at a time including only two phones, a computer, and either an Xbox or Netflix. At my old place I had a nighthawk and I was pretty satisfied, but when there was people watching Netflix I would get ping spikes pretty regularly. Connecting through Ethernet is not an option as the location of the router is far, but also I want to make sure my roommate is not lagging either. I don't know much about routers and am just looking for a simple solution ideally under 200$ [link] [comments]  |
| Posted: 14 May 2019 01:06 PM PDT I don't know if i'm in the right place to post this so apologies to mods if i'm wrong. In 2017 I met a guy who had something like the title and thought it was the coolest thing ever. I don't remember what he was running; could have been a raspberri pi. Now, I want to be that guy. I have ~8Tb of media that is ready to be used on a 3.5" HDD (10Tb minus formatting). I imagine about 20+ connections would be necessary at a time. What product would make this work? I just need a bit of direction. [link] [comments]  |
| [advice] small office setup - 2 computers to shared drive/folders Posted: 14 May 2019 08:12 AM PDT Hi guys, I have a small 2 person office. I have a Mac and my co worker has a windows pc. I have optimum internet and I supplied my own modem and router. I have a nighthawk netgear router. We have one printer that I hook up to via usb and she hooks up to wirelessly to print. We are trying to find a solution that lets us share a folder/drive to easily look up and save documents in a shared drive/folder. Any suggestions on the best way to set this up. Dropbox and google drive just aren't efficient enough. Im sure there a simple solution I'm missing. Thanks in advance [link] [comments]  |
| Posted: 14 May 2019 06:49 AM PDT Im visiting my mom and trying to get her home network working right. The problem (i think) is that when everyone is home at the same time there are probably 5-10 wireless devices actively bring used and 20+ wireless devices connected at any given time. She just switched from att to spectrum and while peak speeds are much better, both att's and spectrum's routers shit themselves and frequently disconnect everyone for a few mi utes and/or dont work at all. At home i have a nighthawk x10 and att fiber that works great (i bypass the att router completely - it is connected to one of the x10s LAN ports with a WAN bridge to pass the authentication signal only). Im tempted to set my mom up with the same, but a $400 router is a hard sell. Realistically, how powerful of a router does she need to support 20+ devices? Should I jyst look for the cheapest 4x4 mu-mimo fouter i csn find? [link] [comments]  |
| Posted: 14 May 2019 06:37 PM PDT Hi everyone. I've been reading a bit about MOCA and utilizing coax cables in the home to extend my network WiFi coverage. Can someone help clarify something for me? I'm moving into a new home that is not wired for Ethernet. I'll have Frontier FiOS for Internet. (Preciously Verizon Fios in Florida.) I believe I'll have a cable router—the router in the living room connects directly to the coax cable. Question 1: Can I potentially use any coax cable in the home to get service from the ISP? Every coax cable in the home should be the same right? Frontier will install a box in the garage (I believe an ONT?) but I don't get exactly how that connects to the rest of the house.... I'm not a huge fan of WiFi extenders for obvious reasons like speed and reliability. But I can't just have the single router reaching every part of the house. How exactly can I use MOCA in this situation? Is it as easy as buying something like the actiontec MOCA adapter? Can I plug an old Linksys wifi router into this and have it in bridge mode to just propagate a WiFi signal for the local network? I'm a bit confused still how all this works. Thanks a bunch for any help! [link] [comments]  |
| Posted: 14 May 2019 09:51 AM PDT Hi Reddit, I'm looking for advice on which network switch to buy with the current home network I have. I'm not well-versed with networking and I recently got a fancy router from my ISP in a lucky draw (Netgear XR700) which led me to making some pretty bad choices. My ISP plan is 1Gbps down / 1 Gbps up. I have a Plex Media Server (PMS) running at home, and after getting the XR700, I bought a 10GBe PCIe card from Asus along with an SFP+ to RJ45 module from FS.com to connect the PMS to the router's 10G SFP+ port, thinking the router's inbuilt switch would serve gigabit streams to each of the local connections. The FS module turned out to be a dud (inconsistent connections) and I don't really want to pay for the official Netgear SFP+ to RJ45 module. This led me to consider purchasing a 10GBe switch, and I've narrowed it down to 2 choices:
The current idea is to connect 2 of the XR700's 1GBe ports to 2 of the Netgear switch's 1GBe ports by Link Aggregation, so that the connection between the router and switch is 1 Gbps down / 1 Gbps up. The PMS will be connected to the 10GBe port on the switch, and the rest of my network to the 1GBe ports. The idea is to give the PMS the full 1Gbps upload speed when streaming to remote users and also 1Gbps streams to local users. Is this correct? Further, I would like to ask about the switches itself:
Any other recommendations are welcome! Please correct any misconceptions I have as well, I'm a noob in networking and I'm quite lost. D: [link] [comments]  |
| Posted: 14 May 2019 02:44 PM PDT I live in a rural area that has very limited internet access. Up until recently it was copper DSL at speeds below 1 mbps down, like 300 kbps up (yes, with a K). A local cell company does hotspots for pretty reasonable - 3G speeds but true unlimited (no deprioritization, throttling, etc.). This gets me to about the 5-10 mbps down and 1 mbps up range. What I'd like to do is bond (not just load balance) two connections together to increase speed. I need bonded connections vs load balancing because I want two stream hi def movies without issue and maybe stream some online games (I have an NVIDIA shield, and they offer cloud gaming as a service, but it needs speeds just outside what I get). I contacted Mushroom networks but they don't do anything residential. The device is like $2k and the service is about $250 a month (on top of the internet service you're already paying for). Is there a way to do this myself? Like, can I use two connections to VPN to one machine "in town" that gets cable internet and combines those two connections together remotely? I'm familiar with setting up servers, etc., but don't know where to start on this. [link] [comments]  |
| EOL ASUS AC56U that works fine. Should I upgrade? Posted: 14 May 2019 02:43 PM PDT As the title states. I currently own an AC56U since early 2014 that's more than enough for me, but ASUS is no longer supporting it, and I'm mainly concerned about security since it no longer gets updates. Should I upgrade or can I hold off for another 9 months until the AX standard is finalized? I normally buy routers once every 4-5 years, and hesitant about buying a new router months before the AX standard is finalized. My main concern is security due to my device being EOL.

| No patch panel vs. coupler patch panel vs. traditional patch panel Posted: 14 May 2019 02:31 PM PDT Hi all -- From what I can tell, there are the three options for people who install a home LAN:
What are your thoughts on these options? Patch panels don't seem to do anything, so I'm confused by the second and third options. Regarding traditional patch panels, why is cutting open and fraying the cable considered "clean" compared to having proper jacks on the cables and plugging them in? I also read that the frayed end of the cable can only be a half inch or something to stay within spec. How is it possible to connect the individual wires to a patch panel (or keystone jack) with only a half inch to work with? [link] [comments]  |
| Need Help Interpreting PingPlotter Posted: 14 May 2019 06:11 PM PDT I'm trying to troubleshoot my computer's wifi connection which has been laggy with voice and video calls. I'm confused by the bottom graph in the [PingPlotter](https://i.imgur.com/oAdN7sb.png) results, which shows that the latency is peaking every 15 seconds according to a regular pattern which repeats every 4 minutes. What could this mean? [link] [comments]  |

| NVMe M.2 bottleneck on XigmaNAS (NAS4Free) Posted: 14 May 2019 05:25 PM PDT I'm chasing after a bottleneck on one of my NAS4Free servers (or rather, testing for bottlenecks before I invest coin in any upgrades). I've been itching to see if its possible to saturate my 10Gbe connection (an NIC to NIC direct connected affair) with M.2 SSD's, and I wound up upgrading a 512GB NVMe quicker than I thought, so I thought I'd run some tests. I have the M.2 set up with NAS4Free in a Dell T7500 with a pre-existing NAS4Free install in it. This server usually gives me around 300-350mb/s (for both read/write) with my RAID-Z2 of 7200rpm drives. I threw the M.2 in as a striped drive with no RAID just for tests – it's a Samsung PM981 M.2 with a theoretical 3000 MB/s read and 1800 MB/s write cap. It's installed in the box with a PCIe adapter card (GLOTRENDS PA09_HS) which, near as I can see it, seems to be a direct passthrough device which doesn't require any drivers. I already tested the card and confirmed its speeds when I had it installed in a Windows box. This T7500 NAS is direct connected to my main box with Mellanox Connect-X2 PCie NICs running static IPv4's. Jumbo packet on Windows is set at 9614 and receive buffers are 4096; these are the max settings for the Mellanox. On Xigma, I have the MTU at 9014, with "mtu 9014 rxcsum txcsum tso4 lro" set. The main box has a Samsung 970 EVO M.2 in it and reads/writes at 2,200-2,400mb/s, so that's fine as well. However, when running AJA System Test (biased towards video editing tools) on Windows to check speed, I'm seeing anywhere from 480 to 600 MB/s write speed to the server's M.2, and 530-580 MB/s read speed. This seems abnormally low – given everything I've set up to now, I would think that the 10Gbe connection should be saturated enough to be the weak link at this point. This said, I've been cycling through all the possible bottlenecks, and I'm a bit baffled. The only one I can think of is the Dell T7500's PCIe 2.0 limitation, but the adapter card is on an X4 slot. Theoretically, it be capping out somewhere in the 1,500mb/s range to the server itself, and at least 900-950mb/s when tested to the Windows box, shouldn't it? Curious to hear if anyone has an idea.

| Ethernet connection bottleneck speed at 100mbps Posted: 14 May 2019 01:28 PM PDT Hello, I recently upgraded my home internet to 1Gbps. I plug the coax directly from the wall into the modem/router(XB6-T) that xfinity provided and a cat5e ethernet cable directly from the modem into my motherboard. My wifi speeds are up to 600Mbps, but my desktop speeds are capped at 100mbps. My network card(Intel® Ethernet Connection (2) I219-V) is on my motherboard (rog strix z370-f gaming). My drivers appear to be up to date.I have tried setting the 'speed &duplex' setting to 1.0gbps but after I adjust that it says there is no connected ethernet cable. I have searched for a couple of hours for a solution but have found nothing that is specific to my situation.https://i.imgur.com/Rd5TCuX.png Any insight into what could be causing this would be much appreciated!

| Advice needed on network switch Posted: 14 May 2019 01:06 PM PDT Dear r/HomeNetworking, I moved in a new appartment that has UTP connections in the wall in almost every room. All connections lead to the modem, which has multiple utp connection. I want to connect my TV, PS4, Nvidia shield, Sonos and our digital TV box to a single utp connection, however in this room there is only one connection in the wall. I was thinking to buy a UTP switch which i can connect to the wall connection (connected to the modem) and the gear I mentioned above (so 6 ports). However there is a lot of difference in all the switches I see, with a lot of features I don't know if I need. Things I do: Download games for PS4 and playing online Netflix Music I only use one thing at a time on this UTP switch except downloading a game on the ps4 while watching a movie. The reason I need the high speed is mostly for the 4K movie streaming from my PC which I can't do over wifi as the files are to big which results in to stutter/buffering . Which switch do you recommed budget is around 50 euro/dollar but if something is bit more expensive but worth it, the I can adjust. [link] [comments]  |
| Which router has parental controls that do this one thing? Posted: 14 May 2019 04:46 PM PDT It's common to be able to set a schedule for network access for your children, but I haven't seen a router yet that allows me to temporarily bypass the schedule with one tap of an app to allow temporary access. Does anyone have suggestions for their favorite router that does something like this that seems so simple? I've tried Netgear, ASUS, TP-Link, about to try a linksys tonight after I return the TP-Link. [link] [comments]  |
| [Adivce] For stronger Wifi signal in basement Posted: 14 May 2019 12:59 PM PDT Hello all, I recently moved back home and had to set my PC up in the basement. I have no problem with using Wifi but it seems the connection and latency is fairly poor. I was looking into it and saw many different wifi boosters, range extenders, etc. and have no idea what to choose. There are things that are priced anywhere from $40-150+. The wifi adapter I am currently using is the NETGEAR Wireless AC Adapter AC600 Dual Band. I do no think this is the issue but instead of where my PC is setup in my house. Our router is a NETGEAR AC1750 Smart Wifi Router. My main question is what would be the best way to get better connection in the basement without hard wiring a lan connection? Any help would be great, Thanks! [link] [comments]  |
| Router and modem upgrade reccomendations Posted: 14 May 2019 04:37 PM PDT I live in a decent size home with devices(laptops, PCs, mobile devices, home automation devices) scattered throughout the house. Most days, especially when multiple devices are connected to a VPN for work, the wifi gives out and disappears from available networks. The router then has to be reset for it to appear again. I believe the issue may be due to very outdated router/modem combo that hasn't been upgraded in a long time. The current router is a NetGear N750(model #WNDR4300) and the modem is an Arris TM822. After looking these up, it seems like they were released around 2012/13. Could anyone recommend a decent router/modem combo for a house with many devices(12-20) that will support gaming, streaming, work? If not a specific router or modem, what I should look for in my decision making process? Considering a mesh network, but have always preferred LAN. [link] [comments]  |
