Hi guys, I have a found a easy and simple fix for getting the wifi on Q. Special thanks to Andy, Error and Jett Kasper, without them I wouldn't have worked out this solution. The steps are quite simple.
You need to have a working Q rom first.

NOTE: DO AT YOUR OWN RISK. Its been tested on US998, LS998 converted to US998 and H931 converted to US998.

The files needed are twrp dataimg or int2sd, any Q rom and jett's magical backup.

If you flashed pie kdz. Then you should decrypt your internal storage by formatting it. Or if you installed zip just make sure your phone is decrypted. Then you don't have to format internal storage again.

Also backup your persist, Persist-lg and modem partitions. Before switching to Q.

1. First of all check which recovery you have. It can either be twrp dataimg or twrp int2sd. If you have this move forward, if don't then flash it in fast boot mode.
2. Extract Jett's magical backup in the twrp backups folder.
3. From stock pie clean flash any Q rom. And let it boot.
4. When it boots. Reboot your phone to twrp.
5. Then in twrp you have to restore a backup. Its the jett's magical backup you have to restore in the recovery.
6. This backup has three partitions. Persist, Persist-lg and modem. Restore this backup and reboot your phone..

Now you will have working wifi om Q.

Tada! Enjoy the Q roms...
