Same here.
Just sharing my experience: I'm on OOS 4.0.3 with root on my OP3 and have a 2.4GHz router at home with 200MBps d/l speed subscription. I used Root Browser and changed gChannelBondingMode24GHz=0 to gChannelBondingMode24GHz=1. My speeds have not changed. I am still getting about 25Mbps to 27 Mbps.
~25mbps is much lower than even regular narrowband 2.4GHz usually gives you. There's something seriously wrong somewhere with your setup, I'd troubleshoot the router at this point.
My router is in the basement and the speed test was done on the 1st floor. If I go to the basement I get 80Mbps.
Alright. In that case, it's not something the phone can help. The problem is, the basement ceiling absorbs/blocks the wifi.
IF the router has rotatable antennae, try to set them so that the antenna's end points at the wall instead of the ceiling, so wifi is directed upwards.
IF that's not possible or doesn't help at all, I'm afraid only relocating your router or perhaps buying wifi extenders for the other floors can help.
We moved into a new construction home last year and had the builders wire three Ethernet ports, two on the first floor and one on the second floor. The feed for these ports is from the basement (router) and that's why we have the router in the basement. I have noticed that the orientation of the antennae makes a difference. I currently have them diagonal but will try facing them more perpendicular, towards the walls. Still able to stream Chromecast on the second floor but I'm sure w/a faster connection, Chromecast would be faster. Hardwiring the TV to the ethernet port is much faster than wifi. At some point I'll have to upgrade to an ac router but since the current one is sufficing, haven't done so yet.
@dreinulldrei your module is not present in magisk repo! Could you please link the module here?
It's still in the repo, available on GitHub. The reason it's not seen in the Manager anymore is that it hasn't been updated to the latest module template.
It does work even on the Nougat version of OOS. @dreinulldrei, you really should apply for the repo because this is a solid mod.
