SR9 long ping times

I have 40 or so clients on 900 using MT and SR9. Everything was fine until one day everyone's ping times jumped to 4 digits. I have tried changing channels (2 only with 802.11b which is another issue) but no help. Noise floor is a -94, not great but customers have -80 signals or better yet poor ping...

All Compex is not something I have tried but that's a good idea. 2511's are not an option because they are prism based and they won't do nstreme which I run exclusively. If it weren't for nstreme I would gladly drop the 2511's in because they definately don't have this problem.
