Outside of the link at the bottom of the OP, can anyone recommend any online guides or tutorials to better understand the basics of networking?

My folks have ATT Uverse internet and TV. Their internet use is currently browsing/email/youtube. They live in a multi-story townhouse and as expected they get shift Wifi coverage (Uverse modem is in a 2nd floor bedroom) I'd like to get them set up for better wifi coverage. Here is what I'm envisioning, please tell me if I'm off base:
That should be doable, right? Does anyone with Uverse have similar experience?

Volguus posted:While cable is always better than wireless, if running the cable over two floors is a big PITA, you could also buy 1 AP and one extender.Set the AP near the modem and the extender on the first floor somewhere where it gets a reasonable enough reception that it can amplify. Thanks. I'm going to try and convince them to let me run the cable but I'll keep the AP/Repeater idea in mind. Now I need to read up on how to set up a router to act as an AP with Uverse. astral posted:Is their u-verse TV running on coax or ethernet? If it's coax, and as long as nothing's changed since I read about this a while back, you can actually use the ethernet port on the TV boxes for your own networking purposes (with a caveat or two, if I remember correctly) to potentially spare you from having to run some cables. Hmm. I'm not positive. I guess the other TV boxes get their signal via wifi from the main modem/router. I'm out of state and won't be able to get my hands on everything till the Christmas holidays but I'll check that out. Hughmoris fucked around with this message at 04:15 on Nov 16, 2017 |

Can I have a router act as a bridge and a WAP? I'm staying at an AirBnB for the next two weeks while I try and find an apartment. The wifi signal is shite, and I don't have access to the home's networking equipment. I have a Netgear R6400 router. I put it in 'bridge' mode and connected it to the home wifi, and then used a cable to connect it to my desktop. My desktop speeds are much better. I was hoping there would be a way to ALSO have it boost the wifi signal, so I could connect my wireless devices to the R6400 nearby and then it would use wireless to communicate to the home router. Is this possible? Thanks!

Forgive me ahead of time if I'm not using the right terminology here... Recently when surfing the web I'll have issues with webpages not loading on the first try. The error I get is usually DNS related. If I refresh the page then it'll load no problem. The issue occurs on multiple browsers, and seemingly multiple computers. On my Netgear R6400 router I have my DNS manually set to 8.8.8.8 and 8.8.4.4 . I've also tried setting it to the CloudFlare DNS and the problem persisted. It seemingly affects other applications. I almost had to reschedule an online-proctored certification because of a DNS issue in the application. Any ideas on how I can narrow down what could be going on?

This morning I tried the /flushdns again, and I set my DNS on my desktop instead of it deferring to the router. That might have fixed the problem, haven't seen the usual issues since then.

DerekSmartymans posted:The fun thing is we have 10 homes on our 4 mile long street that have been praying collectively just to get Comcast to lay cable from its current terminal point to our road. Our choices are cellular or satellite. Even motherfucking Dialup doesn’t work. 56k won’t stream YouTube, but our 1920s-era copper wires will not even push 28.8K reliably! And many of us have horror stories about the practices of 1st/2nd gen satellite providers. I downloaded an Ubuntu ISO and our house was throttled to unusable bandwidth for 13 days. For just under $100/month. And it was 2down/0.5up with a minimum latency under perfect conditions of 1000ms. Many, many really fun games with multiplayer , and later no-physical media downloads were straight up impossible. My GoG library is full now of games like Mass Effect-supposed to be fun, but I never had access to what many well regarded games from 2005-2018 because of data caps. Skyrim was great because it was a DVD with no DRM, and later on the (smaller-sized) mods kept it fresh. WoW was ok for PvE, but it took 10-12 months for me to learn how to stealth and backstab in PvP because you had to psychically predict the placement of your moving foe 1.5 seconds in the future! Always on DRM for single player PC games (Splinter Cell: Conviction was the worst!) made games unplayable for months until they patched it out due to sales and returns. Have you looked in to Starlink? Seems to be a great option if available to your area.

Any advice for troubleshooting intermittent connectivity issues with a router in bridge mode? I have a Cox modem/router combo downstairs. Upstairs is my netgear r6400 in bridge mode connected to my desktop with ethernet. My desktop internet connection will stop working at seemingly random times, no rhyme or reason. None of the blinking lights on the netgear router change. Other wifi devices in the house work just fine when this occurs. The connection won't work again until I reboot the netgear bridge. I tried rolling back firmware to a previous version, no change. The desktop appears to be pulling both IPv4 and IPv6 addresses. Not sure if there is much to troubleshoot other than "buy a new router". Hughmoris fucked around with this message at 15:37 on Dec 5, 2021 |

Hardware chat advice needed. Renting a new place. Cox cable, internet is slow. Hitting 90 mb/s when I'm paying for 500 using their hardware. There are at least 5 coaxial outlets in the place, and below is a picture of the splitters/connectors for the townhouse. Am I likely correct in assuming that the signal is coming off the street and in to the red box amplifier "Input" jack?  I only have internet, and only care about the best signal to the modem. Theoretically, I could get a female-to-female connector and connect it directly from the street to a single room? Hughmoris fucked around with this message at 21:55 on Jan 6, 2022 |

Bob Morales posted:Yes. They usually won't even support putting the cable into a splitter or whatever. skipdogg posted:Yes, you want the best signal possible to the modem. Can you post the modem stats page? Doh. Realized I forgot to post the picture. Thanks for the advice, I'll head back over there tomorrow and see if I can get rid of all the splitters and connect from street to one room. And I'll see if I can get in to Cox's panoramic modem stat page.

CopperHound posted:Except in there very likely case that the install is f'd, you probably have another coupler with a grounding connection somewhere before that. Partycat posted:And somewhere where the power supply is for that amp. The input cable to the amp looks weak sauce, I would second a guess that this is coming off a tap or block somewhere else and not right from street feed directly - it could come from a tap in the complex/village but looks self installed IMO. Yeah, its a row of townhomes. Just going to take a stab at getting the best possible signal before I pay $100 for their tech to come out. I looked at the Cox Panoramic wifi manual and I didn't see anything on how to view modem signal strength. I'm just going to disconnect those two monstrosities, use a female-to-female connector and connect the red box "input" directly to my room to see where I stand.

To wrap up the Townhome Tales: went back to the residence today. Didn't touch anything, and I was hitting 480 mb/s on wifi out of the 500 I'm paying for. I'm hoping it was just slow provisioning yesterday that led to the initial low speeds. Also, I found one of these in the rooms that was unplugged. Plugged it in and suddenly the outlet in another room started working. I've never seen one of these before, guessing its powering the red box amplifier posted earlier?  All in all, the issued Cox Panoramic modem/router seems to do everything I need to it to do. Sucks that its $13/mo but given how expensive a quality modem and router is now days, I might just roll with it for now.

Partycat posted:Yep that looks like a power supply that you'd use for one of those for sure. Looking at the earlier photo, it looks like each of leg of that splitter cuts the power in 1/4, with a slight gain potential from the amplifier with its +15dB forward for that frequency block, so maybe the idea is unity gain if you're serviced by some appliance in the complex. It attenuates a bit going back up but not by much. Thanks for the info. That is a realm I know little about. At this point I have everything connected where I want it, and if the speeds stay up without drops than I'm going to call it good. Until I'm tempted by their GIGABLAST!!! package. I really don't need those speeds though... maybe I do.

I'm a networking novice trying to understand DNS a little bit. Can someone explain, from the screenshot below, why resolving the dns for SA gives me a small entry but resolving the dns for theverge.com gives me all that extra info?

astral posted:A record vs cname record. Sniep posted:SA being a small entity and on a small budget (relatively speaking) is doing things "the old way" by just having a couple A records sent of their dual load balanced clusters/sites. The two entries you see are static and point to two distinct locations by IP (I don't think they're anycasted but maybe) Ok that makes sense, thanks!
