Hey guys so I used to use openwrt for my cable internet that I had a few months ago. Now that I am on att fiber internet. I want to know if the approach to set up openwrt router is the same as it was for cable internet. Just want to enhance my network quality with SQM for fiber.
How do you expect us to know this ?
because this is a openwrt forum where people can ask questions and advice??? Lol

All telepaths are on vacations. For now you're stuck with an old procedure when you describe your hardware/software configuration and your problem.
... or you can wait for telepaths to return to their duties.

As pointed out, all crystal balls are being serviced, sorry.
We can't help you with (literally) "how to get from X to Z".
You could however try https://openwrt.org/docs/guide-user/network/wan/isp-configurations#at_t.
We need some info on your subscribed speeds, and what router you have.
Then do a measurement of current speeds WIRED via your router(s) https://www.waveform.com/tools/bufferbloat and post the link with results (it is down under result numbers)
eg any router with gigabit ports will do for basic 300Mbps subscription, but you need to get more selective with gigabit connection 
Well Iâm using the NanoPi R6S and I have a 1 gig fiber plan. I know when I had cable it was pretty straightforward with modem in bridge mode then just hook up my router to the modem. But now that I am with att. They donât offer true bridge mode but rather their own implementation which is ip pass through. So I set that up and connected my openwrt router to it. I did read the wan isp config page and it talked about setting up vlans for att setups but I want to know if thatâs actually necessary??
trial and error ?
or wait for an AT&T user to come across your post...
google will probably work too.
Rome2, ignore the trolls who offer nothing but sarcasm. You just got 1 gig fiber, congrats on that. You are excited (rightfully so) and it shows.
I have at&t fiber too, the only thing I can help you with is my experience. You already set up pass through which is good.
I looked into the vlan setup and from what I can tell that is required if you want to bypass the fiber gateway entirely and plug the openwrt router directly into the ont (fiber to ethernet adapter) . I never did this myself. Never had a reason to.
If you want to do it however, the instructions are here. gateway bypass .
You can also google âat&t gateway bypassâ
Iâm sorry I wouldnât be of much help but at least I tried unlike some others.
I have AT&T fiber with a bgw-320 gateway. there is no âbridgeâ mode, but there is âip passthoughâ which comes pretty close.
since the default IP nange that the gateway hands out is 192.168.1.X, you will have difficulty using your openwrt router as a router, since the WAN canât be i the same subnet as the LAN that it will hand out.. so your choices are to change the LAN subnet on the AT&T gateway, or change the default LAN subnet on your openwrt device. i chanfed my AT&T gateway to hand out 192.168.10.X. my openwrt router is handing out 192.168.1.X as default.
when you first connect to the AT&T gateway, your WAN address will be 192.168.10.X, and you will effectively be double-natted. if you set ip passthrough on the AT&T device, and then release/refresh your WAN connection on your router, you will get the WAN IP for your AT&T gateway passed though to your openwrt routerâs WAN interface.
if you want to go with this setup, then be sure to disable wifi on the AT&T device, and there can only be 1 device getting a passthough address. so dont connect any other devices to the gateway. you should think hard about how much firewall you want to take down on the AT&T device. if yo want to handle all firewall functions on your openwrt device, that is fine, and much more strightforward for port forwarding.
iâm sure others on this forum can correct some of my terminology and steer you in a different or better direction, bu t this has worked well for me for a couple years. the symettric speeds are fantaastic. your chokepoint will now likely be within your network, not outside. have fun

vlan tagging is not necessary when using AT&T's IP passthrough mode. Just select DHCPS-fixed & enter the MAC address of your nanopi r6s's WAN port. This is AT&T's version of bridge mode & helps avoid double NAT.
On your nanopi r6s the wan interface should be configured as a simple "DHCP client" to receive the public IP address from the AT&T gateway.
Finally install qosmate for your 1gbps speed. Good luck

Thanks man. There is a lot of trolling on here. To think that you could find some level of maturity on the forums but I guess not. And yeah I wasnât sure if that was absolutely needed or not. For now I set it up the way I usually would with cable internet. So far things have been rock solid and bufferbloat has been kept to an absolute minimum but of course there are some occasional spikes which I think are normal. Who knows. But I really appreciate you for responding!
Ahhh I see and can you elaborate on release and refresh the wan connection? You mean doing a simple router reboot orrrr???
Restart the connection, if that goes nowhere restart service called ânetworkâ in luci/system/startup
Reboot is usually easiest.
