It's a pretty solid 2.4Ghz-only N router. Best part is DD-WRT. However, it only has 4MB of flash memory.
I switched from WNR2000v2 units in WDS running DD-WRT, to E2500 units in wireless bridge mode running Tomato.
The E2500 has 8MB of flash memory.
(Btw, these are MB qtys of flash memory. When you can buy a 4GB flash drive for $4 retail, don't you think that the router mfgs could maybe toss us a bone and put 16MB of flash memory standard?)
