I tried two different units before returning. Neither worked as well as a WRT54GS in the same (demanding) application.

The SRX400 card I tried to use was buggy at best, and the connection was not at all reliable using the Linksys software. the XP drivers worked better (surprisingly). Typically, I would have to eject the PCMCIA card, re-insert, and restart the Linksys software to even have a chance at a connection. The connection strength and overall reliability were not nearly as good as the WRT54GS, even trying different configurations, frequencies, security settings, etc.

Net: Don't bother with SRX200. SRX400 is a beta quality product - wait awhile for real software and reliability. Absolutely not worth more money than the WRT54G or WRT54GS product line.

Works very well for me. Have been using a VERY early model of the WRT54G for years, and have had great service. Was apprehensive about a change, but Linksys (Cisco) pulled through, again. System installed without a hitch (well, except for a modem power-down), and the signal is very strong, even deep into our backyard; almost 150 feet away from the installation. That's going through a huge floor-to-ceiling brick fireplace, too. I've heard of slowdowns associated with these routers, but my hardwired speeds have not been affected, and the wireless speeds are within 10% of those.

I bought this unit few months ago. It provides better range, but it seems to have some issues with VPN passthrough. I have been trying to connect to my office thru VPN. It just does not work. I have contacted their tech support a couple of times, but none of them was able to help me out. Anyone else experiencing the same issues that I have, and any workaround for it?

I have the same situation with my WRT54GX2. I can not connect to my company's VPN. I have searched for another forums but I am just accepting this Linksys model does not support VPN through wireless.

Hopefuly the Linksys guys will resolve this situation in a new firmware.

I purchased the WRT54GX2 to do VPN over wifi, and almost took it back after not being able to get it to work over wifi (wired VPN worked fine). I am using the Nortel Contivity client, which uses IPSec, in this case UDP port 500, NAT tranversal over port 4500. Linksys tech support had me try many different settings for port triggering, port forwarding, etc., all to no avail. The last thing tried actually identified the problem. I had wireless security set for WPA2-PSK using AES encryption. I dropped the encryption back to TKIP, *** and VPN tunneling succeeded ***. So, I'm operating the AP in a very slightly degraded security, but using a strong, very random 63 char passphrase. I'm not sure if the IPSec and AES compatibilty is an inherent issue yet, but am hoping a firmware update from Linksys will resolve the issue completely.

Another deficiency with this router is the inablity to disable an active IP from the DHCP client table, especially for wifi. I would like to see this functionality for development and test scenarios. This option exists in quite a few other Linksys routers.

Other than these two things, I'm happy with the performance of this router. It's wifi range and speed is great, throughout a 3 story house.

Hope this same condition resolves your VPN problems.

I am having the same problem with this router, but, I can connect, but it drops my VPN connection about every 30-60 minutes. I had my cable company monitor my signal and they "said" I had no drops from them and my company says it is not them either. Can anyone provide the actual settings for this modem. I have no idea what the last poster is talking about, to technical for me..... Thanks.
