AT&T Fiber finally became available in my area, and I’m scheduled for an install tomorrow afternoon.

I know that there are certain tips and tricks to make sure everything runs fast and smooth, but I’m not very tech savvy and would appreciate any advice.

I’ll be changing from Cox GigaBlast internet…I currently have a Motorola modem and a Google router and mesh system. Thanks in advance.

have them install the gateway where you want it and pray the service in your area is good. That is all you need to know.

Edited for wording:

Bad service from a provider like ATT is unlikely. Sometimes larger issues happen and it filters down, but on the whole, fiber internet is a very stable way to go..Equipment fails, but i never count that as bad service, because sometimes its the users equipment thats the issue and they blame the ISP..

That would be incredibly inaccurate. There are tons of bad fiber services out there. At&t specifically has issues in several regions of the US right now with regular gateway outages and connectivity issues.

Outside of at&t, there are a ton of crappy fiber ISPs. Many smaller fiber ISPs dont even have IPv6 implemented in any form (not even 6rd) along with tons of outages. Brightspeed/centurylink/quantum are easy examples of outage issues with fiber providers.

How is having IPv6 implemented going to improve the fiber service?

More and more services/functions are going IPv6 only every day. So if your service can't connect you to everywhere you need, that is a poor service that needs improvement.

i have a fairly active plex server with about 25 people streaming movies from me.

i had a 1gbit but watched my traffic and at no time did it even come close to 500mbits so i am saving $15/mo by dropping my fiber speed to 500mbit and haven't seen any drop off whatsoever.

I was always happy with at&t 300/300Mbps service but when I had to the opportunity for 1Gbps at $40 for life, I decided that was OK. Nothing ever saturates it except for Genshin Impact updates.

My pixel loses full functionality of google play services when SLAAC IPv6 is not present. It will fail to execute backups. This is just one example.

Yes, this example is clearly a sign of the need for all ISPs to immediately set up IPv6 routing...

You asked for one, I gave you one. You then proceed to bitch about it. Sounds like you made a stupid request.

In the event you do get more serious about the subject, just do some googling. There are many smart technologies out now that rely on IPv6 exclusively because they can "just work" and avoid NAT issues. Several features in tvOS, iOS and Android are built this way. You can google them if you want. But I'm sure once you find them, you'll just move goalposts again.

you didn't give me a link, you complained about your phone, which could be an it issue or a your home routers issue..

ironic, right ?

Maybe you need to focus on your LAN, then work your way out...Based on other topics you speak about on here, I'm starting to think you really are slightly behind

It takes 5 sec to google the google play services issues when IPv6 is not available. Your ignorance is not my problem.

It would be very difficult to have IPv6 fully functioning if you didn't have it on your LAN. This thread was about WAN services.

Can you not use a normal router if you get ATT Fiber? You have to use their gateway?

Makes my Asus Mesh router obsolete? Seems like it would be weaker?

Yes you have to use their gateway, but you can put it on bypass mode where it acts as just a dumb switch. From there you can use your own router.

There is a way to get rid of the router completely, but it is a hack and not approved by ATT. You do this by buying your own SFP+ module. Those modules cost about $200. An SFP module is basically a little transceiver. It has a laser in it that transmits light for upload and a photodiode in it that receives and decides light for download. ATT gives you an SFP that works on their router, but you can buy third party ones.

I’ve had AT&T fiber in 4 different houses in 4 different cities. My parents and in-laws also have it. It’s been rock solid at all of those locations. Fast, never goes down, low latency. My wife and I both work from home on video calls all day, I’ve got 9 security cameras uploading 2k video 247, we exclusively stream, etc and it never even hiccups.

With a couple of our older installs the gateways the sent us had an issue with NAT table limits, but I could bypass the gateway using specific networking gear. The new ONT Gateway combo device they send out don’t have those issues at all for us.

How’s WiFi with just the gateway for areas far from the gateway?

I’ve never used their gateway for Wi-Fi. I’ve used Amazon eero and unifi stuff. Eero is a surprisingly solid set it and forget it mesh system.
