Wireless Bridge Speeds
Hi All,

Could anyone confirm that the speeds that I am currently experiencing over my wireless bridge are what I should expect or whether something is wring with setup?

I have BT Infinity coming into my lounge and plugged into one of the Ethernet ports is a CAT 5E cable that runs up to the loft and into TP-LINK TL-WA701ND 150Mbps Wireless N Access Point. This has an external TL-ANT2409B 9dBi 2.4GHz directional antenna that is mounted on the outside of my property. I am powering this using PoE from the lounge, about a 10m run of cable.
In the garden I have a log cabin which has the identical setup as before but the TL-WA701ND is plugged into a switch. The Access Point in the office is powered directly from the mains. The antenna does have a 5m extension lead on it to get the signal back to the access point. The distance between the 2 is no more than 20m and there is a clear line of sight. Both devices have been directed towards each other.

The bridging has been setup and the two devices talk to each other and I can also ping the server out in the log cabin.
The setup on the Access Points is as follows:
Operation Mode = Bridge with AP
Channel = 13
Mode = 11bgn mixed
Channel Width = 20/40MHz
Max Tx Rate = 150Mbps

There are some further settings available Beacon Interval, RTS Threshold, Fragmentation & DTIM which all have their default values still.

Testing the speed between the house and the office though only shows 10 to 20Mbps.

Is this the sort of speeds that you would be expecting or is there anything glaringly wrong with the entire setup?

Thanks in advance.

I cannot answer your question, but have some suggestions for testing segments of the totality.

If the access points have a 'N only' mode try that.

If you have a laptop with 'N' wireless capability try it outside as near to the access point's antenna as possible. If that has a much better speed then try it again as near as possible to the wireless bridge's antenna.

If you get better speed with that last test then see if you can move the wireless bridge temporarily to connect it directly to the antenna to eliminate the 5m extension.
