Link Drops

5.2dBi Mast Omni at Central Site, 13.5dBi at 2 Remotes. ONe remote a problem. Distance to problem remote is .6Km. Signal strength shows 50%.

Keep getting Lost Authentication, then it associates again. Dropped speed down to 1Mbps., but still drops out evry 3-4 hours.

There are high Tension Power lines running above the path between the two site. Is this an issue?

Re: Link Drops


It is possible that the power lines are an issue but check everything else first.

Which firmware version are you using ?

Do you have a high rate of CRC errors or discards ?

What is the signal quality ? ( run the antenna alignment test)

Anything close to the frensel zone ? what showed up in your site survey as potenial problems ?

How long is your coax at both ends.

What do you see in the channel activity test ? Have you selected the least congested channel ?

Has this always happened since it was installed or just started

I know this is a lot of questions but these are the first things you need to check when you troubleshoot bridge links
