Hello there, :wave: Iâ€™m from Europe; Iâ€™ve just bought the brand new WRT300N v2.0 (to replace my old WRT54GS v1.1). WRT300N is running firmware 2.0.11 Tow wired clients and three wireless clients are connected to my WRT300N (2 Wifi. B and 1 Wifi. G) with WEP 64-bit encryption key. I use PPPoE for my Internet connection (Orange). All others settings are set to their default values. The network works fine and is very stable, but I have small issues. 1. From a wireless client, I canâ€™t access/ping other swireless clients (they are unreachable). :cry: The only wireless machine I can reach from the wireless clients is the WRT300N itself. The wired clients can access/ping the wireless clients successfully. I havent changed the security defaults settings (except WEP 64-bit). My WRT54GS v1.1 works flawlessly with that.

(PC0-Wireless to WRT300N) 2. I own only Wifi B and G clients. According to the user manual I must set: Radio Band to Standard in Basic wireless setting. But when I do that, none of the clients can reach the WRT300N (I have tried several standard channels). I must set the Radio Band to Wide and it works. Do you know why ? Please help me (Point 1 is very important for me). :help: Thank you very much Have a nice day Best regards Denony. Edit : I have contacted the Linksys Live Chat Supportâ€¦ They asked me to change MTU, Fragmentation and RTS Threshold, Beacon Interval, Channel, â€¦ They asked to hard reset the WRT300Nâ€¦ But it still doesn't work. Iâ€™ve replaced the WRT300N by my old WRT54GS and all work fine nowâ€¦ May be the current WRT200N firmware is not 100% compatible with 802.11g and 802.11b.
