    Home Network Mistake - Cooling Options for Structured Media Center

    https://preview.redd.it/m4dt03y235391.jpg?width=2268&format=pjpg&auto=webp&s=f7afb6534eed2645c4b560013d30442df8096ee3

    In the Summer of 2020 my COVID project was to run ethernet throughout my home for computers and POE cameras and terminate all connections to a structured media center. I decided to locate the box next to the electric panel in my garage where the coax and POTS lines were all home run wired to. I live in Pennsylvania where we definitely have 0 degree winter and 90 degree summer days. I was a little concerned about wild temperature swings and especially heat, but since I never worked with POE Switches before I never thought equipment would get THAT hot if I purchased a "vented door". Well... that was a mistake.

    Now I will say in the winter if I close the door to the cabinet the equipment will keep a very reasonable 45-65F, and my summer solution thus far is to just open the door and let the equipment breathe. For the most part that's fine until the dreaded sweltering 90+ degree days. On these days my Unifi Cloud Key approaches 60C and is very hot to the touch, as is my Unifi 24 port POE switch. My temporary solution is to just grab a box fan and blow air on it, which does seem to help but isn't the nicest solution.

    Are there any easy solutions that anyone has used with these such as a simple USB powered fan pointed out the top vent or something to keep pulling hot air away from the equipment? In a perfect world I'd love to just keep the door closed all year and continuously pull the hot air out of the box.

    My speeds randomly slow down until I reboot my modem (Arris SB6183)

    Posted: 02 Jun 2022 06:04 AM PDT

    I've been scratching my head the last few weeks trying to diagnose why my internet speeds are going from ~200mbps down to 30-50 on wired and 30 over WiFi on both bands from my Netgear router.

    At first I thought my Netgear router was the problem, but reboots to the router never fixed the speed. Only when I reboot the modem do the speeds go back to normal, for a period of time. I've noticed the speeds tank when I'm downloading a game via Steam. Last night for an hour my download speed was stable but then it would go down horribly to 30mbps and remain there until I rebooted.

    I checked my router logs on my Netgear router and found a flood of ACK Scans and the occasional WinNuke attack, I assume this to be normal for Netgear? Am I being DDOS'd? Is my modem on its way out?

    The only other issue I had was an Ethernet port in my room which I only have my computer hooked up to wasn't working until I untangled some Ethernet wires in the attic that somehow caused an issue with the Ethernet port. I'm not sure where to go from here on resolving my issue. I've become more paranoid of a Ddos attack affecting my internet now thanks to those stupid logs. Would greatly appreciate help!

    Non wireless router for wifi 6 access point compatibility

    Posted: 02 Jun 2022 07:22 AM PDT

    I want to set up wifi 6 in my home. If I have a Non-Wireless router connected to 2 wireless access points, do I need the router to be wifi 6 compatible? Or is that a job of the access points?

    Nginx and WireGuard

    Posted: 02 Jun 2022 03:36 AM PDT

    Hi,
    I'm struggling with understanding something that is happening in my homelab. I'm using Nginx Proxy Manager to control access to some of the web pages services I store. I do that using IP address origin to authorise only my LAN and another VLAN (40) I have.

    The machine hosting NGINX is on VLAN 10.

    When accessing a website from VLAN 40, I'd see in my access log that it was accessed by the ip 10.10.40.x (subnet of VLAN 40).

    I have a VM, running WireGuard, that itself sits in that VLAN 40. But when I try to access the same website, the IP that seem to try to access this is 10.10.10.1, ie, the Gateway of VLAN 10.

    I don't understand why that's the case. I'm fairly new in all this. Thanks for your help

    No DNS option in ZTE F660

    I have a ZTE F660 from hathway - and I recently set up a Pi-Hole.

    I followed a tutorial to set up DNS on it, but there's no option!

    Trying to get VLANs working

    Posted: 02 Jun 2022 07:21 AM PDT

    Hello everybody, I have some problems configuring my VLANs correctly on my network. I'd appreciate some support.

    I just can't set the VLANs correctly on my switch (or maybe it's a problem on the firewall's side?) and it's really confusing for me. As I said, I'd appreciate any support, thank you very much.

    Using an OPNsense Firewall / Router and FS S3700-24T4F Switch

    A Strange thing is, I also have a Proxmox server directly connected to another Port on the Firewall and the VLANs there work without problems.

    So that's why I think that it is a configuration issue on the Switch's side.

    My current configuration of the switch

    If there are any questions to the configuration on OPNsense, I'll send the according screenshots into the comments / edit the post accordingly.

    Thankful for any help and support.

    Need a "cloud" printing solution

    Posted: 01 Jun 2022 11:42 PM PDT

    So this is a slightly strange, specific situation - I have a workshop, that I'm usually not at, that has a small desktop PC connected to a USB printer and a USB label printer. Hoping to acheive what I want without changing this hardware, although if someone can recommend a cheap print server I'm all ears. The PC is always on, and connected with a static IP.

    I want to be able to print to these printers, with the PC as a server, from anywhere. What's the best way to acheive this? Thanks.

    edit: I'm a windows and Android user, if that changes anything. Don't plan on doing anything with mobile apps but you never know?

    Advice on 4g dongles for failover

    Posted: 02 Jun 2022 03:23 AM PDT

    Hey all!

    I have an ASUS RT-AX82U which has the ability to use a USB dongle for WAN failover. However all of the "supported" USB dongles on the documentation are waaaay old and you can't buy them anymore.

    I just bought a D-Link DWR-932, and am using a sky mobile sim card (I am in the UK). The device works great as a 4g wifi router, but plugged into my ASUS router, it constantly just says "disconnected". Does anybody have any advice or experience with setting up failover? Did I buy the wrong thing? Is there some setting tweak I can use to "fool" the router into thinking it's a different compatible USB device?

    According to the documentation for the D-Link, it can be used in USB mode or as a standalone wifi router.

    Cheers

    Is SFP worth it for the latency improvements on 5gb fiber?

    Posted: 02 Jun 2022 06:58 AM PDT

    I am upgrading to AT&T's 5gb fiber and I'm wondering if SFP+ is worth it for the latency improvement for gaming. Their modem has SFP and my pfsense box and gaming pc would also be fitted with an SFP nic. This is very expensive, so I'd like to know what the latency improvement is on average.

    Yet another "old router as wifi repeater" request post.

    Posted: 02 Jun 2022 06:44 AM PDT

    Hello everyone!

    I'm moving to an apartment that offers free wifi, but the signal is weak in the bedrooms. I have a couple of unused routers (Technicolor TC7200 and TC7200.20) and was curious whether I could use them to boost the apartment wifi.

    A bit of googling and youtube watching suggested it should be possible, and I feel I've gotten halfway there. From the videos I watched, I can scan for the apartment wifi and enable WDS bridging, but I don't get the option to add the apartment wifi password on the Technicolor routers in the straightforward scan-for-wlans-then-press-connect-way the videos show (these Technicolor routers don't seem to have this feature explicitly obvious, so not sure if there's a workaround or if I just haven't found the right setting, or it's just plain impossible.)

    (WDS bridging seems to be possible though I don't even know what that really means https://www.manualslib.com/manual/1176643/Technicolor-Tc7200-20.html?page=64)

    If anyone has done this with these routers or has ideas on how to, I'd be eternally grateful.

    Adding the YT resources I was using for reference:

    https://www.youtube.com/watch?v=21tRWUvsQ34

    https://www.youtube.com/watch?v=uvc4MPNJGdo

    https://www.youtube.com/watch?v=8-dAxVzClfo

    Also, my routers don't seem to be supported by DD-WRT, Tomato, etc. at the moment.

    Much appreciated!

    Should I go with 1Gbps or higher for my setup?

    Posted: 02 Jun 2022 02:51 AM PDT

    I am redoing my network setup at home, now it consists of an old tplink router switch access point combo. I got an 1.2Gbps service from my ISP recently so decided to upgrade my setup. Xbox one, TV and PC are going to be connected with cables, rest of the devices are going to use wifi. My PC has 2.5Gbit network card and I am planning to get an NAS in the future. For know I will be using modem with router provided by my ISP but I want get an Mikrotik router down the road. I don't know if I should get an 1gbit switch preferably with poe for AP or should I go with 2.5gbit or higher to future proof and use all of the bandwidth I have. Could you recommend some switches I should be looking for? I am new to networking and got a lot of information from reading this subreddit but still don't know what to do. I am located in Poland.

    Help Wanted: New apartment networking layout. Best approach?

    Posted: 02 Jun 2022 02:47 AM PDT

    Hi all,

    tl;dr - brand new 95m2/1000sqft apartment, but it's all cement. What's the best solution for getting wired internet in every room? Also I'm allowed to make minor modifications to the unit, so if you were going to set up your ideal arrangement in this space what requests would you make of the construction manager so everything was set up as nicely as possible?

    I'm not sure if this is the best place to post, since most of the posts I've seen here are about more advanced situations (ceiling drops, multi-floors, etc). My situation is pretty basic, but I would REALLY love some help with this because I feel like I'm missing an obvious solution.

    I'm going to move into a 95m2/1000sqft apartment that's getting built. The floor plan looks like the following:

    https://imgur.com/a/xmdiwlX

    It's European, so a couple differences to the US-centric posts here:
    - The units are in centimeters for some reason. Divide by 100 to get meters. Or divide by ~33 to get feet.
    - The apartment is ALL cement with plaster over it. Floor, ceiling, walls, etc. As far as I know, none of it is done in the usual "create spacing with wooden frames, fill with insulation, and then cover with gyprock". Maybe they still do this for placing the insulation, but there will still be a cement wall at its core. This makes all of my instinctive solutions to running cables inside of walls/between rooms pretty much useless (North American myself).

    What I would like to have is the following:
    - Ethernet connection in the TV room for the entertainment center
    - Ethernet connection in each of the two bedrooms
    - Possibly also HDMI cables running from each of the two bedrooms to the living room so I can use the TV like a second monitor for couch gaming or watching media that isn't available on my TV's apps (running from the desktop in my bedroom).

    My questions are the following:

    1. If I have a choice, where would be the best place to have the apartment's "entry point" of my internet/phone line? ie, where the internet provider will put their box. My first thought is to put it in the top-left corner of the TV room (where the little plant is on the floor plan). Good wifi coverage for the main living room, and already flat against a wall if I need to drill/run cables through the walls into the bedrooms. But it's far from the door, so I don't know how they'll run their cables to get TO that corner. The second idea is to put it in the laundry room next to the entry door (bottom left of the floor plan). This should make it easy for the internet provider to run their entry cable, but this spot will be pretty bad for wifi (again, all of the walls in here will be cement), and also increases the distance I need to run cables from the entry point to the other rooms.

    2. Best place to put the main router? The explanation is pretty much the same as Question 1 above for the entry point - I'm assuming the main router needs to go at the entry point anyway? But perhaps not.

    3. Best way to get ethernet to each of the rooms? I don't think ceiling drops are an option, since the space above my cement ceiling is no longer "my apartment" I don't think. Do I run cables along the baseboards? Drill directly through some walls? Other options?

    4. If I want to be able to use my living room TV for gaming from my bedroom's desktop, what's the best way to do that? I've seen other posts on this sub about people using switches of some sort to stream content between screens in different rooms. Would that be a better idea than running an HDMI cable along/with any ethernet cables I'm putting through the walls?

    5. Bonus question: Is there anything I should request from the construction manager? I'm allowed to make minor modifications to the unit, so if you were going to set up your ideal arrangement in this space what requests would you make so everything ran as smoothly as possible?

    If you're still here after this long post, thanks. Any help or suggestions people can offer would be greatly appreciated. I feel like there's a lot of potential here, and I don't want to screw it up and have to do something non-optimal to fix it later. The limit of my problem solving is pretty linear (just run an ethernet cable through the wall!). All the filled-up networking boxes I see on this sub make me think that there's likely a better solution to my problem than just running a bunch of cables from my router and calling it a day.

    Thanks all!

    Firewall related questions

    Posted: 02 Jun 2022 06:06 AM PDT

    Hi all!

    Tio preface this, I do networking mostly as a very fun hobby - I am by all means very inexperienced.

    I have a basic idea of what a firewall does, and I'd like to implement it in my home network to tinker with it. However, I need a few questions cleared up before I make the plunge! :P

    How would I implement the firewall? Would it be WAN connection -> firewall -> router, or would the firewall act as a router as well? Are there certain models that do both routing and firewall duties?

    Do firewalls slow down throughput/overall speeds?

    How much more secure am I with a great quality firewall than just my regular ISP router/firewall hardware combo?

    Thanks folks, keep this awesome sub up! :)

    Asus ZenWifi AX Mini (XD4) 2nd and 3rd node not getting more than 200mbps

    Posted: 02 Jun 2022 05:20 AM PDT

    Hi guys,

    I bought this 3 pack for my home network and I'm not getting the speeds I want.

    The internet speed from the main node to ISP is 500mbps which is my current plan. From my main node to the 2nd node, the speed is 800mbps. And from the 2nd to the 3rd, my pc is connected to this 3rd node by ethernet, is getting 1000mbps download speed. So everything here is as expected.

    But when i do a speedtest, on my computer, phone, any device that is connected to the 2nd or 3rd node, im not getting more than 200mbps on 5g network.

    Any one has this problem?

    Horrible experience trying to set up ISP Hub as Modem, and 3rd party TP-Link as Router. Please can I get some help to attempt again?

    Posted: 02 Jun 2022 04:58 AM PDT

    I want to have my TP Modem Router as main one due to ISP ones not being great.
    This happened yesterday and I had read it was easy, but turned out to be hell.
    All I read as the 'easy steps' was, change VM to modem mode, connect TP-Link, reset and voiola. But that wasnt the case with me...

    I'll try and outline the steps I took to see if you can advice what went wrong.

    I have Virgin Media Hub 3 (I will call it VM) and a TP-Link AC1200 Modem Router FYI.

    1. Turn VM Hub into Modem mode via IP 192.168.0.1. (this was fine and it turned purple/amber).
    2. Turn off the VM Hub.
    3. Connect the TP-Link via ethernet from TP's LAN4/Wan port into VM's port 1.
    4. Let TP Modem Router turn on. This then displays the TP-Link wifi name on my PC (all good so far).
    5. This is maybe where I mess up? I move 3 Ethernet connections from VM's Hub into the TP-Link. Maybe you need to do one by one? Or setup the TP first, then move the rest?
    6. I Navigate to TP's IP 192.168.1.1. This should be the final step/process to finalise the TP Link connection with Virgin Media. But this is also where the issue/confusion occured.
      I was trying to setup everything but couldnt find anything on Google that explained these steps (I did have this setup previously when I was w/a different ISP so was aware of it).
      I somehow bypassed this section (or changed something to Dynamic IP) and it showed the split SSID's. After that (almost the final setup section) it was not showing a completed/successful connection (I didnt get a screenshot of this).

    I spent nearly an hour on this and switching between Hotspot (to have some form of wifi to research this all)
    .I also had issues going back to VM default wifi (after a hard reset it worked but it added to the stress).
    So I'm back to square one and would like to attempt again to get it all working.

    Would apprecaite any help/step by steps! Thank you

    How can I monitor my VM's network traffic?

    Posted: 02 Jun 2022 04:35 AM PDT

    Say, I have Linux installed on bare metal and host a VM via QEMU+KVM. Is there a way to monitor VM's network traffic?

    I know next to nothing about networking so I'm mostly looking for general guidance (as opposed to a hands-on tutorial).

    As far as I understand, there are two broad ways:

    1. My VM gets its own IP address on my home network.
    2. My VM's traffic goes through the host (I reckon it's called bridged?)

    I'd guess that the 1st way is what I'd need for monitoring from a hardware firewall and the 2nd way is what I'd need to monitor from the host. Am I right?

    At the moment I have no hardware firewall (only a fairly standard router from my ISP) but I'm open to buying it if necessary.

    What software tools could I use on my Linux host?

    Streaming UDP or TCP?

    Posted: 02 Jun 2022 03:39 AM PDT

    Noob here. I get the basics of both and I've seen a lot of answers on when to use each one. UDP is always suggested to be used when something is "live". So skype video calls etc. So why is it that many live-streaming things use TCP?

    For example a twitch stream, CMIIW but does it use TCP? Or is it because you can afford to lag behind a twitch/youtube livestream but you can't really afford to lag behind a skype call or playing an online video game?

    Also, can an application use both TCP & UDP for different parts of an application? Say you have an app that lets people listen to a live radio broadcast. Is it possible to have TCP for the connection between the radio and app and then UDP for the connection between app and listener or is it just more ideal to have TCP on everything since you can afford to lose 10 seconds when listening to the radio? or is udp better in this scenario?

    How do I limit the number of connections on my Wi-Fi router.

    Posted: 02 Jun 2022 03:17 AM PDT

    I'm trying to limit the amount of unspecfied connections on a given router from 15 to 20 users at a time.

    I've tried DHCP limiting where the available IP address range is limited from 0 users to around 20. Although this kind of works, it dosent allow new connections once user IP addresses have been established.

    In other words, if the DHCP range is set to 20 users, only the initial set of 19 unspecified users can connect at a time, and all new connections trying to access the router will be refused.

    Although this works in theory, it turns out that if one of the initial current set of users turns of or disconnects from the WIFI, another device cannot connect to it. And it's only when the router reboots, that assigned IP addresses will be refreshed and a new set of users can connect.

    Is there a way to allow brand new connections beyond the initial 19/20 set of connected devices to join the Wi-Fi network without rebooting the router? So far it seems the only way to limit the number of maximum connections on a network is by DHCP IP limits or Subnet mask.

    Both of these methods require rebooting of the Wi-Fi router to allow for new connections to join, despite old connections being disconnected.
