Cisco 877w - how can I change channel?


I have a Cisco 877w and it seems the coverage seems to fluctuate between 11mbps to 54mbps between different hours of the day, I'm just wondering if a neighbouring wireless network could be using the same channel?  Or my settings are not optimal. How do I change the channel and/or are these settings not optimal, if I have missed some important config please let me know:

interface Dot11Radio0
description **MyLan Wireless Network**
no ip address
encryption vlan 1 mode ciphers aes-ccm
encryption mode ciphers aes-ccm
ssid MyLan
speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0
channel 2462
station-role root
rts threshold 2312
no snmp trap link-status

Re: Cisco 877w - how can I change channel?

Before you do such radical moves, just check what signals are around you.  Netstumbler is a good free proggie.

How far are the clients from the wireless access points?
Are they behind brick/cinder blocks/cement walls?

If you want to nail down the channels to use, I'd recommend you HTTP/HTTPS into your router.
