wireless bridge problems

I have setup a wireless bridge on our network that are using the following:

1.1 Linksys Wireless Ethernet Bridge
Model #: WET54G

1.2 Radio Labs WiFi Backfire Antenna
Model #: BACKFIRE14

1.3 Hawking Technology Hi-Gain Heavy Duty Antenna Extension
Model #: HAC30N

1.4 Pacific Wireless Antenna Pigtail(N Male to RP-SMA Male)
Model #: CA100-NM-RSMAM-12

These items are used on both ends of the wireless bridge at a distance of approx. 130 yards. Our problem lies in the connection reliability. We have %100 uptime on the bridge that is physically connected to the network, but constantly have to power cycle the other bridge (remote building) to get the connection back. It usually stays up for at least a few hours (sometimes shorter) and completely drops. When pinging the remote bridge, it usually hangs around 35ms and can spike to around 150ms. It is usually at this time that the connection can timeout and drop. I have lowered the RTS threshold to 1200 and switched to 802.11b (since i heard the signal is better over longer distances). Is there anything that I am missing?

NOTE: When I look at the signal strength on the bridge I can never get a read-out of the signal strength. Is it proper to be using two bridge units or do I need to use an AP with a bridge on the remote side only?

Hi,

If you do not see the receive level at either end then the antenna's are not aligned. The antenna's that your using have a very narrow band width, and high gain, you must be seeing the 3 db signal from the other end... There are several ways to align the antenna's. First off they must be line of sight... with no tree's in the path. Second the antenna's should be more then a foot or two above any building or tree's. So here we go...

1. connect to the router to monitor the receive signal strength.
2. mark the present position of the antenna, one line on the mounting pole and a center line on the mounting bracket of the antenna.
3. move the antenna clock wise 1 to 3 degree's from the position you just marked, very very slowly, monitor the receive signal, if the power is increased at any point then stop and mark that point. record the signal level. Now move the antenna until you get to the 3degree mark, note the power increases or decreases. Now swing the antenna, back to the 0 mark or the orignal position. Do the same for the counter clock wise swing. recording the receive level. when you reach the 3 degree point. lok at the recordings and move the antenna, back to the most receiev signal that was recorded. Lock down the antenna. Now do the same for the up and down movement of the antenna. Once done, move the antenna back to the highest signal level. Then lock down the antenna. Now do the same for the distance end. If done properly you'll have a great signal and no move down time....
