hey i have a rb433 running on 4.3 witch developed a strange prob , it feels like i am being capped at a speed of exactly 79.5 kb/s doesn't matter what program i use , even tried other pc's and operation systems no luck but when i change settings , any setting inside the rb it reconnects and jumps up to my usual speed of around 400 kb/s but after awhile its back down to 79.5 and there it stays i know i am not being capped from the other side and i have reset the configuration multiple times anybody got any ideas cause i am all out ?

If you try to reset the RB, and use default settings and still experience the same issues, then try another RB to see if you experience the same issue. If so, I would suggest you to try other cards and see if there are changes.

Trying 2-3 different cards might help in determining what card works for you as well as to narrow down the possible problems you are facing.
