i recently purchased a used WL500W-Router and installed DD-WRT (24preSP2).

I realised now that my signal quality is never higher than 50 % even when my laptop is located 2m from the access point. I run the access point in "only-n" mode.

Anybody got the same issue?

Things I tested:
- Testing another laptop with g-modus = same result = poor signal quality
- Adjusting tx-power = minimal change
- adjusting antenna option (vertical, horizontal) = even got worser

Things I want to do:
- Installing Original Asus FW to see if problem is also there
- Installing Oleg FW

I searched on the internet and this forum and could not find any thread regarding this issue.

Best Regards
