Using two TL-WA5210G I would like to connect both of them as repeaters, but in repeater mode I can't use WPA/WPA2 encryption. The manual states that WEP only is supported in repeater mode, which of course I noticed after I bought them.

I am thinking of degrading the security from WPA to WEP, enabling MAC filtering, and hiding the SSID. I know the whole configuration is insecure and every one of those measures can be easily circumvented. In addition to the above is it possible to create/use a watchdog to deny any other connections ? Maybe using a shared extra security token ? Other options ?

From my search so far, DD-WRT seems to support WPA in repeater mode but my AP isn't supported. Alternatively, I could use them in bridge mode but the cable installation would be a pain.

Anything I haven't think of ?

You could buy proper enterprise class repeaters (Hint: the target audience of SF...) Other than that: are power line adapters an option to avoid cabling? –  Hennes Aug 10 '12 at 14:21
Power line adapters is not an option. The best solution seems to use bridge mode, buy another AP, and deal with the cabling. But why does it have to be like this, since other TP-Link devices support WPA in repeater mode ? –  dtouch3d Aug 10 '12 at 14:38
