FP3 with FRITZ!Box 7590 user here - similar (same) behaviour - Wifi connection very flaky with phone switching between 2.4GHz and 5GHz and ending up at 2.4
Fritz selected the higher channels (116 and up) as it would’ve been alone there. Else there are 10 (including mine) 5GHz networks now sharing the lower ranges.
After pinning the channel to 56 phone and box are good to go.
re:Channelwidth - 160MHz width is NOT allowed
@moldowan: you’re not alone ; thanks for starting this thread. I’ll try to investigate further later this evening.
Nobody suggested a channel width of 160 MHz. You could try between 20/40/80 though. What I’ll try is see if I can put it on 20 or 40 with channel 116. You could play around with it.
Also, the fact that you can see other networks on channels does not mean they’re having a good signal (you should check their RSSI). If their signal is weak, you won’t have much (if any) interference with them.
Allow wireless channels with 160-MHz channel bandwidth (5-GHz frequency band)
Increases the maximum radio channel width from 80 MHz to 160 MHz and allows the latest Wireless AC devices with 2 x 2 antenna technology to double their throughput rates.
The Fritz router seems to automatically use 80 Mhz channel width because it always shows a (max) channel usage of 4 (when 116 is selected: 116, 120, 124, 128, or when 52 is selected: 52, 56, 60, 64).
Each of those channels is 20 Mhz wide.
I can confirm the 5Ghz channel problem on the FP3 with the Fritzbox 7590. When using auto channel, the phone would not even connect to the network at all. Switching to channel 52 made it work properly in n+ac mode.
Hi there,
i have been following this discussion since i received my FP 3 in December.
I always had connection issues with my FP3 at home (Fritz.box 6490 Cable @ 5Ghz and a Fritz.Repeater 310). However, i have no issues at work (Eduroam @ 5 Ghz - no clue what specific hardware that is).
My FP 3 does only connect to the Repeater (only supporting 2.4 Ghz) but never to the router itself. disregarding of my distance to the repeater, even when i´m in close proximity to the router.
I tried to change the router settings as described in this threat and a similar one - however no change what so ever - i hoped for the update not change either.
i guess this issue is really related to the WiFi-chip in the FP 3 and the fritz.box as all other devices get along pretty neatly with the 5Ghz network and switching between access points.
Hi, my FP3 Wifi on Channel 116 was very flaky too. Fritzbox 7560 OS 7.12. On Original Android and on /e/ Version 0.9p2020051454091. Fixing 5GHz to Channel 52 did resolve the issue for me.
greeting, bodo
I had a Fritzbox 7581. The 5GHz could not connect to the FP3 or the FP2 of my friend.
Now I have a Fritzbox 7590 and the setting for the wifi channels is on automatic.
I get a very good signal on channel 100, so is the FP2. I am in Tilburg, the Netherlands.
I am on /e/. Didn’t have the Fritzbox 7590 when I was on orginal android.
Could reproduce
Fritzbox 7590 in an environment with several 2.4 GHz networks and very few 5 GHz networks.
Fairphone 3 on current patch level randomly lost wifi connection on channel 124 and 116, was being automatically steered to 2.4 GHz by the router. Switched 5 GHz Autochannel to 5 GHz channel 52 enforced and haven’t had a single drop since. I didn’t switch on the 160 MHz channel width though.
I also had this issue and pegged my router to a lower 5 GHz channel and it’s been happy since! Unfortunately it seems higher channels are default on public wifi, since those still get dropped and then “disabled” on 5 GHz.
I also can confirm that my WiFi seems more stable (still not perfect), with my 5GHz configured to use channel 52 on a new AVM FRITZ!Box 7590. Are there now opensource WLAN drivers we could integrate into the FP2/3 LoS builds @chrmhoffmann?
Hi guys, I wanted to say I was having some issues with my internet connection, which became most apparent during internet calls. The test here may help you to see if your settings have improved your phone’s connection (see the response times).
Just for info. I have a FritzBox 7530
a) you can rename the 2.4GHz and 5GHz SSID so you can connect to either.
b) Eventually I disabled the 5GHz in the FritzBox settings and I have no problems with the 2.4GHz connection,
c) I do have to restart the phone if I switch wifi off on the phone which I imagine is a seperarte issue
; thanks for starting this thread. I’ll try to investigate further later this evening.
