Lost Connectivity

I have point-to-point wireless link with AP350 and WGB350. The distance is 2 kilometers. One place have 3-5 PCs and the other place have one Server. They share SQL Application. The problem is: after 3-5 hours the connection is lost. In this situation I must reboot the AP350 and the link go up and communication is OK. This is occur 2-3 time at the day.

Maybe some know how can I solve this problem?

Rgrds,

Re: Lost Connectivity

Check out if the software versions running on AP350 and WGB350 have any compatbility issues. One thing you can try is upgrade the software on bot devices and then check.

Re: Lost Connectivity

OK. I solve the problem with replacement the AP350 with BR350 in AP mode. Although this is expensive solution, now I have consistent and faster point-to-point connection. I think that my mistake was long distance (2 km, maybe more). AP350 can properly work up to 1 mile (1.609 km). I appetite this in practice (on field).

Thanks Pengke11 for advice and cooperation!

Re: Lost Connectivity

Hi there,

I also have a similar problem with my AP. I have a WGB350 connected one mile away from a AP350 and every 5 hours (may vary), the WGB is disconnected from the AP.

I'm using standard authentication (Wep 128 and SSID is enough for us). The radios does not show a big amount of CRCs, but some radio retries may occur sometimes. However, the radio signal is really strong between the radios. I'm also using radio firmware 12.03T on the AP and 8.84 on the WGB. A co-worker told me that downgrading the AP to 11.23T would solve the problem. However I want to be sure it is the best move.

Here is the log from the WGB. Do you have any idea about it? Do I really have to buy a BR350 to replace my AP?

Thanks!
