iPhone wifi slow on AT&T fiber

Looking for a solution to an issue with wifi on my home AT&T Fiber network 1000 Mbps. This only occurs with iPhones connected to the my home wifi. The majority of the time my iPhone X is very slow when connected to my home wifi (10 mbps or less). The exact same behavior occurs on my wife's iPhone X as well. Only if I disconnect and reconnect to the wifi via the phone directly or resetting the router does the connect start off fast for about 5 minutes or less.  Does not matter what the signal strength is or where in the home the phone is located.

Other connected devices, such as my Macbook, TVs, Firestick, etc. do not get a slow connection. They get 200+ Mbps over wifi.

Connecting to other wifi spots that are not our home wifi the wifi works as expected and extremely well on the iPhones, which leads me to believe there is a setting / recognition from AT&T router or service that  is specifically slowing the iPhone. Does anyone else have this problem?

- iPhone connects to the 5ghz band

- Tried manually specifying the DNS server to use, such as 1.1.1.1, on the iPhone

- Tried assigning IPV4 address to iPhone when it connects, rather than letting the router choose

- Changed channels of wifi and used AT&T mobile app to auto-optimize channel selection

- Reset of router does not resolve (ARRIS BGW210-700, Software version 1.8.18)

- When wifi is turned off on iPhone to disconnect from home wifi, LTE connects and is instantly faster

Update: I got the two pack Orbi mini from Costco (they were on sale for $130), and set it up as an access point and the difference has been like night and day on my Apple devices, also I’m getting a decent signal throughout the whole house. They had the regular one on sale as well (3 pack for $300) but these were good enough for me.

I have not personally tried the Google Wifi product but on the DSLReports.com Uverse forum there's been a few comments about running that behind a BGW.  One user said it sucked, another said it wasn't that bad (didn't seem like a ringing endorsement to me) and one claimed that he pulled it out because once the streaming traffic on his home network picked up he started seeing big slowdowns, much bigger than would be expected given the traffic.

 

So, not exactly a clear cut winner or loser.  If you really want to go that way, buy it from someone with a decent return policy.  Give it a good test and if it doesn't do the job, return it.

I ended up buying an Eero mesh system (1 Pro + 2 Beacons) based on reviews, especially the Wirecutter's rave:

 

https://thewirecutter.com/reviews/best-wi-fi-mesh-networking-kits/

 

So far, so good. Setting IP passthrough on the router to the Eero was pretty easy. There's good resources online:

Eero also has docs and offers customer support:

 

https://support.eero.com/hc/en-us/articles/207988076

 

One of the nice things about setting up your own mesh system is you can configure the DNS server (I've set my network to Google's 8.8.8.8 and 8.8.4.4, primary and secondary respectively), as opposed to being stuck with AT&T's DNS servers.

 

Will report back here if I run into any issues, but so far so good on day two. I'm getting solid WiFi throughout my home, and no longer have to constantly turn my WiFi on/off on my iPhone when moving across the house (as I had to with my Arris + AirTies setup).

Thanks for reporting back on your progress.  It's good to have a data point that sounds pretty positive so definitely keep us in the loop should things change.

Glad to have found this post. I have the Pace 5268AC with AT&T Fiber 1000. I've had this service since July 2018 when we moved. At first it was awesome but I had enabled passthrough mode to a NG Nighthawk AC1750. We have a 5/4 3200sf house but the modem/router were perfectly central in the middle of the house in the laundry room. This setup worked well for a while then it got slow and I performed speedtests, finding out that the passthrough seemed to cut down the 1Gpbs a good bit to, either due to the interface on the NG or from the Pace, not sure which. So I went back to using the AT&T modem only and that too worked well for a while. Ever since one of the iOS 12.X.X came out it *seems* we started having issues with Wi-Fi Calling and general connectivity. It would come and go but as of late, these last 2 or so months, its been noticeably worse to the point I'd rather use my 1-2 bars of T-Mobile LTE than rely on the Wi-Fi connection. Even friends and family with iPhones who would come over complained. My wife was losing or not receiving text messages on-time, etc.

We have a total of 25 devices made up of various smart plugs, Alexas, MacBook, 3 Roku Ultras running 4k content, Samsung Smart TV, HP Laser Printer, Wyze cams, Ring doorbell, some other random stuff. All that stuff seems to work fine except for the iPhones.

So I've been considering the mesh solution but only if I could wire to the different APs. From what I hear though this isn't required as the mesh systems have their own backhaul radio that doesn't interfere with the standard 2.4 or 5 signals. If I could afford it I would go Ubiquity as it seems everyone who has them loves them. Might even still go with that, leaving the AT&T modem as the router and disabling the wireless, letting those 2 do the work.

Glad to find this post as I was seriously starting to question my sanity!

You have to remember, due to Apple thinking qualcomm was cheating them and charging too much for their modems, they dropped Qualcomm modems and moved to Intel modems. Intel modems in iPhones just don't perform very well. Apple keeps trying to tweak them with modem firmware updates, but that has had very little affect on their performance. Apple realized their mistake and completely dropped their (Edited per community guidelines) against Qualcomm and agreed to using Qualcomm modems beginning in 2020. When Apple was using both Intel and Qualcomm modems, Apple had to throttle the Qualcomm modem because they were twice as fast as Intel and they didn't want people complaining about how much slower their Intel modem was.

Bottom line: Make sure you have the latest IOS update installed so you have the latest modem firmware. Hopefully this is the last year we'll have to put up with this Intel modem issue.

did anybody find the configuration problem? And no it’s the the WiFi ch’s or IPv6. Router is doing something . I believe it’s the phone adapter that causes it but I didn’t test it for long . Using the router without it connected to router.

I had a similar issue with AT&T Fixed Wireless. Browsing and streaming was fine on all except iPhones. iPad Pro was fine. Running a speed text on my iPhone showed 25-30mbs which is the max I can get here, though browsing was still slow and videos would always buffer. After lots of trial and error I noticed that compared the wifi connection settings between my iPad Pro and my iPhone, "Configure Proxy" was turned ON on my iPhone and OFF on my iPad. I switched it off and now my phone loads like it should.

did it continue to work? I found out when I disconnect the phone adapter and restart router it fixes everything. But once I plug back in starts again. I’m gonna see if when I plug it back in if that makes the iPhone proxy turn on. I have it disconnected and all iPhones running fast and the proxy says off .

I figured it out. I have the iPhone X as well! I went to the router, then home network, then MAC Filtering, then MAC Filtering Entry scroll to find your device, then select of the 2.4 GHz and leave the 5 GHz selected. You will then see it on the MAC Fliter List with an asterisk next to the 5GHz! Then put the 5GHz on Whitelist. It worked once I went on Instagram and noticed everything was downloading faster! Also I left the IPv6 on.

I found the solution.disconnect the phone adapter restart router is fixed the lag.

But the only thing that’s (Edited per community guidelines) is once you connect the adapter back problem comes back. So who ever AT&T expert said this router don’t support apple talk something is absolutely wrong!

Has anybody found out why the adapter causing this? I use sonic and AT&T provides the service .
