| Posted: 01 Mar 2020 07:34 PM PST I posted this a bit ago but I continue to have issues. Thinking that the cable was messed up, I got another brand - same problem. Any advice? The problem: I bought some CAT6 cable, along with passthrough plugs, but I'm having a lot of issues getting it to work. I've made several different lengths (1ft, 3ft, 10ft, etc.) and while they all test ok on the cheap RJ45 cable tester I purchased, they do not work when plugged in to a device. I was able to get one 2ft cable to function properly, but have made about 10 others that don't work at all. I'm using T568B (I tried a T568A as well and it didn't work either), all the devices that I'm testing on work with store-bought cables, there are no issues with my router, my switch, or my access point. I have tried on two separate CAT6 cable, so I don't think it's just the box I got was defective. I'm really at a loss. Any help would be much appreciated!

| Trying to change my WiFi router to an AP but need something else to use as a router Posted: 01 Mar 2020 07:26 PM PST Hoping someone can help me understand what kind of devices can be used as a gateway. I am setting up my own home domain/server and this is my stuck point. Right now I have DHCP and dns being handled on server 2016 but my nighthawk router is giving me a headache. I think I'm just going to turn it into an AP but I can't get internet to work without it in router mode. I went and bought a Netgear managed switch to circumvent this issue and I'm going to try to set it up tonight, did I even get the right layer device? It is a Netgear GS108PE [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||
| Wifi doesn't load twitter videos on iphone. Help! Posted: 01 Mar 2020 06:03 PM PST Hi all, i've had this problem forever (across different iphones, and multiple ASUS routers (88u and 68u)). Basically, SOMETIMES, like 40% of the time twitter videos won't load over wifi. it's really annoying and i have to momentarily turn wifi off to let it through. I discovered today however that using a VPN on my phone helps. While this is a workaround, it's not a solution. Any help? Relevant router settings below:

| Should a DOCSIS 3.1 Cable-modem improve my Bufferbloat performance? Posted: 01 Mar 2020 05:41 PM PST I have a Comcast 300Mbps connection. I recently switched to Arris SB8200 DOCSIS 3.1 cable-modem because I read it has improved latency. I test it using fast.com and still get around 400ms latency under load. Is this just a limitation of Comcast network? Could this be due to my router which is an old Asus RT-AC66U just not keeping up? [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||
| Should I use a 2nd router, access point, or WiFi range extender? Posted: 01 Mar 2020 05:40 PM PST I live in a 4-bedroom off-campus student apartment complex. Each room has an it's Ethernet connection. The router is in one my roommates closet, sitting in a metal box that's bolted to the wall. So accessing the router itself isn't possible. I'm no expert, but that seems like a terrible place to put a router. Anyways, I was thinking of getting my own router to hook up in my room. Would this be the best option? I've read a little about access points and WiFi extenders. [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||
| Posted: 01 Mar 2020 12:37 PM PST My old all in one router (AC1200) crapped out on me and I'm in the market for something new. I bought a TP Link Archer C6 for my 1500 sq ft condo and it works ok. This is how my network is setup. Wired: -Desktop -Xbox One -PS4 Wireless: -Apple TV 4K -Apple TV 4K -Macbook Pro -iPad -Printer -Termostat -Android Phone (Google Pixel) So here's the problem. Before my old router (Archer AC1200) bricked itself GTA online used to run great for me. I could join my friends. They can join me. Now with the new one (setup as a DMZ) I'm having nothing but issues joining gta online, joining my friends. It works fine connected directed to the modem. So with that said I plan on sending the router back and buying something better. My question is rather simple, is there something I should look for in a router to clean up things on the wired side? Or is it all pretty much the same and all the bells and whistles are on the wireless side? [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||
| Help with Nest Router and Internet Speeds Posted: 01 Mar 2020 04:08 PM PST My modem is located in my closet, so most routers don't provide coverage for my decent sized house (3500 sqft). When I got the new Nest Home Router, I thought that it would all change, but the main router being in my closet throttled my speeds to the rest of the mesh points. So, I tried moving it outside the closet into the loft. This is the part that gets a little bit confusing. I used our ethernet wired through the walls. So, I plugged the wire going to the loft into the modem. Then I went to the loft and plugged the router into the wall ethernet. (The wire form the modem goes into the wall and ends at the little white thing built into the wall. Bad explanation, sorry). When the router was plugged directly into the modem, I was getting download speeds of 170 Mbps, and uploads of 15 Mbps. But after moving it to the loft, I am getting downloads of 92 Mbps, and uploads of 9 Mbps. The physical distance between where the router was, and where it is now is only like 2 feet, but for some reason, the wire in the wall is throttling my internet a lot. Does anyone have any idea of what is happening? If my explanation is bad, I am happy to explain more in-depth. Thank you for taking the time to read this post.

| Cox Router, how can I set data usage limits per device? Posted: 01 Mar 2020 04:00 PM PST Hi, I am using a Cox panoramic wifi router, so their default interface to adjust settings as well. My issue is that while I was living here alone, I used about 1/10th of the maximum data included per month (1gb). This is even with streaming Netflix or Hulu most hours of each day and downloading games on Xbox. When my boyfriend moved in, the data usage increased but was still well below the max. Now that he has his PC hooked up, almost half of the monthly data usage is used up about a week into the billing cycle. He watches youtube almost all the time but also plays some online games. What I am looking to do is limit the amount of data used by his devices (or even by all of our devices) to avoid going over the monthly limit and being charged extra. Is there an easy way to do this? Could someone please help or point me in the right direction to figure it out? Thanks! [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||

| How do I get ethernet in my room? (and improve internet in general at my house) Posted: 01 Mar 2020 06:18 PM PST OK, so I'm a teen living with my parent's that no nothing about networking so we have been stuck using our ISP provided gateway. I want to upgrade due to the garbage speeds I'm getting. I get around 0.8 Mbps down in my room with WiFi, I want to get Ethernet but they wont let me run a cable into my room. I've considered power line due to it being very simple to use but I heard performance is lackluster and isn't very good. What should I do? I desperately want Ethernet so I can get better ping and faster internet speeds. My friend told me if I had a coax port I could buy a modem and put it in my room so I could get Ethernet... But yeah, what do y'all recommend? [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||
| Improving iSCSI performance on a home network? Posted: 01 Mar 2020 05:30 PM PST Big note: I do not have a separate switch, and I am in no position to be able to afford one. All I have is my home router, which is where all my devices are connected to. I have an ubuntu linux server running on an old pc, it's running a whitelisted minecraft server, a samba share and a iSCSI target which I just made today. I followed this guide. The issue is that my performance on the samba share pales in comparison to my iSCSI target. I by no means have the fastest cables or hardware, but it is the difference between 50MB/s to around 5MB/s. I have heard that a vlan might help, but without a swich or anything, and I doubt it could really be a 10 tims improvement. I have also heard that the windows default iSCSI initiator is bad. I have no idea what a better one would be at this point. The goal of this target was to get around games not functioning well over samba shares, often not loading or having anti-cheats that will try and stop me, so speed matters the most, the data is not of great importance.

| Internet speed with long cable length Posted: 01 Mar 2020 04:48 PM PST I'm currently paying for 25Mbps download speed. I get 21.9Mbps down speed and latency 50-60ms on the google internet speed test with my lap top plugged into my modem via ethernet cable. The telephone pole that my internet cable has to go about 300-400 feet underground to get to my house and I have had lots over problems with the ISP over the years in regards to my internet connection. Last year they finally got a senior tech out who said the installers used RG6 cable and given the 500+ foot run he was surprised we had internet access at all. He instructed that a directional drill install an underground pipe and a minimum of RG11 be run from the telephone pole. I asked that they send their senior tech back out to install the cable but they ended up aending who ever they felt like. Of course the tech was to lazy to go to the top of the telephone pole so he just cut the old RG6 at the bottom by the ground and spliced it to the new RG11 cable. The RG 11 then goes 300-400 feet and into the tap (LB with one pipe sticking into the ground and then other feeding down into my crawl space). Except they were also to lazy to run it threw my crawl space and connect it to the modem. They pulled the RG11 through the tap from the ground but did not continue and push it threw into the crawl space. They just cut itcut it right there and spliced it to the old RG6 again outside. To make it worse they actually cut it a bit to short so now the splace sits below the LB in the pipe and I can now see ground water covering it. So to recap i now have... -RG6 from top of pole to bottom of pole 50ft (assuming it connects at the top of pole and not somewhere further). -RG6 to RG11 splice. -RG11 from bottom of pole to tap 300-400ft. -RG11 to RG6 splice (submerged in pipe full of water/ice). -RG6 from tap to modem 50feet (3 random inline splices in crawl space). I have a few questions... Does it make a difference that the rg11 was not run from end to end? Is this likely the reason I get 21.9Mbps and not 25Mbps? Does this mean that if I upgrade to 50Mbps I get say 40Mbps or is the low quality of the install combined with the great distance actually capping the max download speed at like 21.9?

| Setting up Home Network with single point of 1 desktop as single point of (external) connection Posted: 01 Mar 2020 04:33 PM PST Hi, I have a standard ISP-provided (Spectrum) cable modem-router. I want to create a network of multiple Linux hosts (either dockerized or VMs or just entire bare-metal Linux hosts) to a single Linux host (docker container / VM is possible ? Or need entire bare-metal dedicated Linux host?) as a single point of connection to which my other Linux hosts will connect. The idea is to create a mini networking playground from which I can spawn Linux hosts at-will and tinker with them, but with the security of all routing through a single Linux host to the outside world. The idea is also for me to learn about Linux networking infrastructure by tinkering with these configurations in the 'internal network'. Anyone know how to do this? Would I set up a single host as a NAT-router thingie? Then connect this host to the Spectrum cable-model-router? How do I connect the other bare-metal hosts to this host bare-metal desktop? Would I need to buy a hardware switch into which to plug all these guys? Thanks in advance. [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||

| Posted: 01 Mar 2020 03:49 PM PST I was struggling with lag spikes while gaming for no reason at all, at first I thought it was caused by interference (I was using 5ghz with 80mhz channel bandwith and my room is very far from the router) so I set the channel bandwith of my 5ghz/2.4ghz 802.11ax connection to 20mhz, which didn't impact my performance but it didn't fix this issue either. I tried to ping my router and I noticed that every 10seconds I was getting 30-70ms spikes while averaging 1-3ms. I thought that it was a router issue but after 3 hours of trouble shooting I found out that it was a wifi card issue. Modifying these settings finally fixed all the spikes:
This setting prevents your wifi card from periodically searching for new Access Points, it is automatically set to "never", so your wifi card is always scanning, this is the main culprit.
You don't need this power saving feature, keeping it disabled may benefit throughput.
It's another power saving feature, it reduces the number of receiving interrupts by randomly merging packets. ( I may have mistranslated the name of this last setting, I can't find info about this settings that are not in my native language) Don't forget to update your AX200 drivers, go to Device Manager>Network Adapters>Intel(R) Wi-Fi 6 AX200 160Mhz.

| MTU change inconsistent performance Posted: 01 Mar 2020 02:47 PM PST I have a pppoe connection and i found on internet saying that changing this value can lead to a performance improvement I tried the ping test on internet and my mtu value is 1450 (even i used the page letmecheckmtu and shows the same value), but if i put this one on router everything loads superfast except that i get super laggy on games. Also my router can autodetect this value and set it to 1480, what makes me even more confused Any idea of how i can get the optimal MTU?

| Can I use my current Netgear Orbi (x2) with this new router? Posted: 01 Mar 2020 01:23 PM PST I'm looking at buying the following router for our new home: https://www.netgear.com/gaming/xr700/ I will be installing this in a closet, then having the electrician install a few ethernet ports throughout the house that will come from this device. This way I can plug directly in on my desktop computer, Playstation etc. I then planned to have a couple of ethernet ports installed in the house (1 upstairs and 1 downstairs) where I would plug in the two Netgear Orbi devices I currently own and use these for WiFi throughout the house. Is this a good plan and can you think any reason why I wouldn't do this? Not sure about the comparability between the two devices. [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||
| Internet connection for a IPFire within a LAN, Routes needed? Posted: 01 Mar 2020 12:59 PM PST Got a short question regarding a IPFire placed behind a Fritzbox. I'm planning to rebuild my home network. I decided to put a IPFire behind my Fritzbox in my LAN. I created 3 different subnets. WAN >> FB >> [Red] IPFire [Green] >> Subnet Do i have to setup a default route (0.0.0.0/0) on the ipfire, so the green's and orange's internet traffic reaches the Fritzbox? In opposite direction, does the FB need additional routes directing to the green and orange interface? [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||

| Upgrade to WiFi 6 now or wait? Posted: 01 Mar 2020 12:31 PM PST I'll be moving soon and need to set up a new network and buy a new router etc. Currently none of my devices support wifi 6 but I'm sure in the next few years go by, I'm sure I'll start getting new devices here and there that supporting it. These routers are pretty expensive right now but it seems redundant to buy one router now and then purchase a similar router again in a few years. Any advice or experience is greatly appreciated :) [link] [comments]  | ||||||||||||||||||||||||||||||||||||||||||||||
| Archer C unable to connect more than 10 devices Posted: 01 Mar 2020 12:23 PM PST Hi, I'm currently using an Archer C6 router to handle wifi in my appartment. Some devices are connected but not getting internet. If I manually disconnect an already connected device, the previous one start connecting to the internet. Also, in the Web admin page from the router, if I try to ping the device using diagnostics tab, it just say "Request timed out" (although the device say that it's connected to the network) It seems that my router cannot handle more than 10 devices but it's just a uneducated guess. Could you help me ? Thanks [link] [comments]  |
