I've been having some trouble lately at my location. Here is a screen shot of last year from inside the hotel with the ap aprox 260' across the street.

The next picture is of recent after the hotel implemented N throughout the building. My RSSI is below -80 but yet, notice the third picture using inssider that all of channel 6 is used by the hotel and I'm on 1 & 11.

Even though the middle picture (channel 1), the amplitude is up to -50 but I'm sure thats not mine because of what is displayed in inSSIDer.

Is there channel bonding going on here?
Would 5 Ghz N with a 18 dbi MIMO antenna reslove this issue?Click image for larger version.
