I have a strange issue I was wondering if someone could shed some light on. I have 2 aironet 1200.. Antenna mounted outside on roof.. line of site across a street to another building.
1 access point setup as an Access Point. The remote 1200 setup as a Workgroup Bridge.
I can setup a ping to the other site and it will ping all day long. As soon as I try to hit an axis camera over there i will loose connection after just a couple mins. I have messed around with frame per second for the camera thinking too much video was killing things. No luck... As soon as I restart the main access point it comes right back up.
Here is some info from the event log on the bridge:
Error Interface Dot11Radio0, changed state to down Warning Packet to client 001b.536c.65f0 reached max retries, removing the client Warning Interface Dot11Radio0, parent lost: Too many retries Notification Line protocol on Interface Dot11Radio0, changed state to up
Any thoughts? I am going to try and get another device over there that I can send large amounts of data from to see if it a bandwith issue...
Signal quality is expessed in SNR. If you have a G radio, I'd recommend a design that will get you 30+ SNR to take advantage of the faster G signalling rates. If you have a B radio, 20+ SNR will do.
You might have have interference despite having a strong signal. This command will give you an indication that you might have interference when you see that the radio is falling back to slower signalling rates.

Also: Try changing the channel. Try a directional antenna.
Thanks for the info. Going to look into it. Perhaps we are asking to much from this unit? (Looking to stream a video feed from a building across the street to the main office.. (about 1 frame per second)...
There is even talk of adding one more camera..
I did make a change and set the main aironet unit in the main building to a Bridge instead of an access point....
I have a number of Cisco 1200's deployed as bridges. Using the A radios, I get real-world throughput of 20Mbits/sec half-duplex. using G radios should get you something similar. The B radio should get you 5.5Mbits/s.
I have these set up as root bridge and non-root bridge pairs. I'm not quite sure what the practical distinction between a workgroup bridge and a non-root bridge is.
