I’m facing the same behaviour with my FP2. Just bought a second Wifi-Access Point (UnifyAP) which caused the original AP (working fine until then on channel 42) to switch to channel 120. To confirm, that the Problem is related to the channel, I measured the FP2s Wifi Receiption on channel 64 and 120 against the reception of a Galaxy-S9. According to the APs Web-Interface, I got the following results:
Reception-Rating (by UAP-UI)
As you can see, the S9 receiption does not change much between channel 64/120 and while the FP2 has a comparable receiption at channel 64, it completely drops at 120.
All measurements have been made in ~1.5 meters distance to the AP
Running on LoS 17.1
PS: Is it worth opening an own topic for the FP2 problematic, as it is a different hardware, or should I stay here?
Thanks a lot, I could have done a comparison between a FP2 and a Pixel 3a, but I did not think about it!
Definitely yes, it is worth to open a new thread in the FP2 section. Although the issue probably will not be solved, because the hardware is as it is, we can collect experiences from other users there.
I had wifi issues with 5GHz since I got my phone. On FPOOS, on Lineage, with two different core modules, on three different routers and perhaps more. Most of the time, it didn’t connect. I didn’t check the channels though.
I’m currently answering you on it, so yes. Though I suspect my second core module to have a defect, in which case I will have it changed. I am also going to get another FP2 soon, and my brother owns one, so I will be able to do many tests.
When I have time, sure I will. For the moment I’m not home though. And I’ll ask my brother for help, he is more techie than me.
Edit: My brother also has a customizable OpenWRT router with which tests will be easy. I’ll keep you updated.
I recategorized the topic in #discuss:fairphone2 as it was originally instead of #help:fp2, because we are more discussing an issue and doing tests than someone asking others for help. I also took the #lineageos tag away, as it is not limited to one OS.
Please tell me if you want to reverse it.
Just tested it again, comparing receiption with the phone in my hand vs. phone lying on hard ground. While I cannot see a big differents between both situations, I recognized that even slightly turning/moving the phone seems to make quite a big difference:
By tilting/ moving the phone within few centimeters, I could reach levels from 5% up to 35% (again ~1,5m distance to the router / channel 120)
