connects in 2.4GHzB but not 2.4GHz B/G?

My SR9 ptp link gets a -80, flashes to -89. During heavy cell phone usage times, I drop connection at 5MHz and 10MHz G mode, so I tried 802.11b. Works fine, even enduring the noise from the nearby cell tower.

I know a cavity filter would help, but I haven’t gotten one yet. I have to make do with what I have for a bit.

My question, why is it stable -85dB in B mode, but if set to B/G mode, it won’t associate in the first place? It will flash in the registration table, but not lock in. Default rates have not been tampered with.

B Mode is more forgiving of interference, bad signal, etc.

Try using 5mhz or 10mhz and only checking the B speeds.

I already tried that. it won’t let me choose B speeds in 5 or 10MHz channel.

I can connect with 5 or 10MHz channels in G mode, apparently not 20MHz channel. What I don’t understand is when set to B/G, it won’t connect. It won’t drop down to B and work, it tries to connect @ 6Mb and drops out.

This was done during a noisy time, but it connected in B just fine. What I’m getting at, why won’t it drop to B mode for a link where there are problems, then go back up to G once signal is better?

I think it only runs in G mode with 5/10mhz bandwidth.

I understand that.

My question is a straight 20MHz B/G question.

If it is set to 2.4GHz B I get an 11mb connection. If I set it to 2.4GHz B/G, it will not associate. It will flash on the registration, briefly show on the status page, then disconnect. It will not connect at 11mb or 1mb when set to B/G.

Oh, Sorry :confused:
I think I would agree with jwcn’s answer.
