iPhone 15 Pro Max Wi-Fi Issues

A friend of mine, systems engineer told me that I needed a new modem with compatible newer technology. He hooked up a new Google HD2 modem to my older Bell modem via LAN cable (behind Bell’s)

Then, follow standard procedure for the new modem (assign a name and password for the new one) Fixed within 10 minutes

If you read the link and specifically the explanations of DFS and TPC, you'll see that for lower channels they may need to change frequency and power levels to avoid RADAR and other sources of interference. This often means the signals may be at levels low enough you can only connect when in the same room as the Wi-Fi router.

Other channels, such as those at 149 and above, are not subject to the same restrictions.

That's not an Apple issue, it's part of the Wi-Fi standard.

I setup a new TP-link axe5400 mesh system. WiFi 6E. Worked great for a day. I am getting “unable to join” errors on 2.4&5Ghz and 6Ghz networks. This is on brand new iphone15 Pro which was migrated from a iPhone 12. I tried the 80Mhz downgrade and the guest network. They worked.

I went ahead a reset all network connections. Changed the network back to 160 MHz and am now connected.

let’s see how long it lasts. I’ll leave 6Ghz off for now.

I have a 15 pro that was getting around 160 mpbs download when a buddy with a 14 pro was getting close to 450. My first thought was an IOS issue so I asked if he was on 17.1.1 and he wasnt; yet my phone was as I had just updated. I told him to update just because I was curious if it was the new update that made my phone suddenly painfully slow when connected to wifi. After he updated to 17.1.1 he ran a speed test and sure enough was getting similar results as I was.

Just because your router is new doesn't mean it has the most up-to-date firmware installed, so you should check.

It looks like the last firmware update for the AXE5400 was released in August, 2023:

I have the 15pro max. It takes so long to connect. My XR would connect to my car straight away but the 15 can take up to 10 mins. This is a real problem as I normally call overseas as soon as I get into my car… any help would be appreciated

dont do 160hz maybe that will fix it. It’s like the airtime not working well over mesh networks. It works well on 2.4 but not 5. I have WiFi 6E gateway so once I get the 15 pro max hopefully it’s faster and more reliable. But Apple is slacking in their network quality.

I'm having the same issue - using my iphone 13 pro and new iphone 15 pro side by side, same wifi, but the iphone 15 pro cuts in and out extremely consistently. I'm usually back on LTE/5G within 30 seconds of connecting to the wifi. The iphone 13 pro works great, never had this issue.

I am also having issues connecting to wifi. I have an Eero Mesh Wifi system. Everything else in my house works fine. My new phone has no wifi. Very frustrating. First backup wouldnt finish, update would not install, now this. I should just send the new phone back.

If you like, or you could try to diagnose what's wrong with your eero, as eeros (depending upon the model) support new standards up to and including Wi-Fi 7… but not always reliably.

Note that eero OS is updated fairly frequently, so make sure you have the latest version installed:

I had the same problem. Connected on the WiFi but no internet. Restarted the router and my phone but nothing changed (neither on 2,4 ghz nor on 5 ghz). And then it hit me. I checked my vpn app and I saw that it was trying to connect on a vpn unsuccessfully again and again (without any action on my part). I closed the app and my internet connection was up immediately! I don’t know if that’s the solution for everyone but it worked for me!

Okay this is bizarre my Apple Pay won’t work messages couldn’t SMS Verizon fixed it how I don’t know but ! I am using an ancient Mac router I love and no issues with WIFI? Omg ! AirPort Extreme so out of date ! And working fine? WiFi ?

I can't speak for Apple Pay, but SMS is a cellular carrier feature, so Verizon was who needed to fix it.

Wi-Fi specs are backwards compatible so even the newest device should work without issue with old access points; the issue is usually on the cutting edge of new standards where vendors may not have implemented the new standards properly.

Thanks! This was my issue as well, although it was the McAfee Security & Wifi Privacy app in my case. Exact same issue that after transferring to a new phone, some apps (but not all) could not tell that I had an internet connection. I also would see the VPN toggle flickering within Settings. After deleting the app, the other apps started recognizing my internet connection again. I also could not see in the Wi-Fi connection in the top bar on the Home Screen until after deleting the McAfee Security app.
