If the patch helps people to get wifi working we should take it, BT coex issues can be fixed in followup patches. IIRC there has been multiple reports about this so I'm leaning towards taking the patch to v5.11.

Yes, it does get the user past the initialization check; however, wifi performance is abysmal according the the users of the repo. It seems that the antenna selection of rfe 2 models affects wifi as well as BT. Applying this patch will get wifi running; however, the users will need to be within 1 m of the AP for it to work!

Without setting to a correct rf module for RFE type 2, you might encounter some problems on 2.4GHz band. In my test, on 2.4GHz band, with the wrong setting, it could not connect to an AP.

Ok, I will drop the patch then. But it would be really nice to enable even some level of support for rfe 2, can't we find some solution? Like disabling 2.4 GHz band for that rfe or something? -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches ^ permalink raw reply [flat|nested] 15+ messages in thread

The E-mail from Realtek (https://marc.info/?l=linux-wireless&m=160255510004938&w=2) says that the patches are ready; however, they need to do some "verification". To me (without proof), that implies a regulatory problem, and it is better that we not enable rfe 2 without the official patches. I hope those patches will be forthcoming very soon.

It is that our QA team tests the some functionalities (performance, BT coex etc.) of RFE type 2. If the test run successfully, the patch will be sent in the next 2 weeks.
