I have two Linksys WRT54G v6. One is running the original software. The other is running DD-WRT v23. I have the same problem with both boxes.
Over wireless connection: (signal is strong, WAN speed is more than 512kbps).
I am able to connect to Goole.ca page. Search something and get some results. When I click most of the search results, it says page cannot be displayed. It looks like it is related to the amount of content of the page being loaded. Sometime it just display part of the contents, usually pictures are missing.
Over wired connection:
When search the same thing and click the links, they are fine.
When I reboot the box, it seems to be better.
Memory status in DD-WRT (just after reboot):
Total Available 77% 6328 kB / 8192 kB  
Free 9% 584 kB / 6328 kB  
Used 91% 5744 kB / 6328 kB  
Buffers 7% 400 kB / 5744 kB  
Cached 25% 1460 kB / 5744 kB  
Active 25% 1424 kB / 5744 kB  
Inactive 8% 460 kB / 5744 kB  
Is the free memory too little?
Any idea what causes the above problems?
Thanks.

How do you have these two routers connected, are both operating as a router/DHCP Server?

More details would be useful..
A separate environment meaning? Two separate modems?

Are they using the same Channels?
Do you have a problem downloading a file or is it just webpage displays?

There has to be something in common to the two if they both have the same problem.....they run different firmware so it's probably not firmware, does it happen on more than one PC or Laptop?

What OS and Service Pack are you running?

one is behind static ADSL connection;
the other is behind fiber optical;
these two routers are far apart => no interference.
