Having a bit of a weird one with my local LAN setup. I recently installed a Cisco 877W router on my DSL2+ connection and all is working really well..

Upgraded the IOS to 12.4 and my wired clients are streaming connectivity superfast at 1.3mb/s.

However, there seems to be an issue with my wireless clients - I can't seem to stream any data across the local wireless connection (LAN) and using the Internet, whilst responsive enough isn't really comparable with the wired connection speed.

For example, all devices are connected to an 8 Port Gb switch on FE0 from the Router with a NAS disk and on my wired clients, I can transfer/stream etc absolutely fine - however, transferring a local 700Mb file on my local LAN estimates 7-8 hours to transfer :(

The Wireless config is as follows :

interface Dot11Radio0
 description WIRELESS INTERFACE
 no ip address
 !
 encryption mode ciphers tkip 
 !
 ssid [MySSID]
 !
 speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0
 channel 2462
 station-role root
 rts threshold 2312

 bridge-group 1
 bridge-group 1 subscriber-loop-control
 bridge-group 1 spanning-disabled
 bridge-group 1 block-unknown-source
 no bridge-group 1 source-learning
 no bridge-group 1 unicast-flooding

All devices are connected to the Gb Switch which is connected to FE0 with the following:

Hardware is Fast Ethernet, address is 0021.a03e.6519 (bia 0021.a03e.6519)

Not sure why I'm having problems on the wireless and I've reached the end of my Cisco knowledge...

Thanks for any pointers!
