WL-500G stability versus Wrt54G

[kolaf]

I am looking for a wireless routers/access point with the ability to provide traffic differentiation (QOS) on a TCP port basis. I will use it as an endpoint at the ADSL side of a 3 km a wireless link with 24 dBi antennas. After reading a lot of forum posts they get the feeling that the cheap versatile routers such as WL-500 g and Wrt54g have some severe stability issues both on the wireless and WAN sides. I also need similar hardware for an additional 200 m wireless link, both on the access point and client side .

Based on this I have several questions:

How is the stability of WL-5 00g (and compared to the WRT 54 G)?

Will WL-500g also function in client/bridging mode?

Is the QoS system functioning properly?

What's this custom firmware I've seen mentioned, is it easy to obtain and install?

Do you perhaps have any suggestions about other the routers/clients in that satisfy my requirements for a reasonable price?

I realise that there is is an extensive list of questions sold would be very happy if you are able to answer any one of them :)

Thanks, Kolaf

As for wrt54g - probably you're aware that "large transfer" causing it to reboot now (this also applies to wrt54gs). The thing is seems to fixable by overclocking device a bit.

The most trouble free router at the moment is WL-500g Deluxe - no hw bug found at the moment.

I am aware of of the large transfer bug, but I'm a bit unsure of the severity of it. Is it so that it only resets itself during a large transfer, and functions properly afterwards? I need a device that it is reasonably probable to does not need to be physically resets often since it will be located somewhere I do not have easy access to.

Well, rebooting means lost of connectivity. It then needs some time to recover, etc...
