It's certainly worth a try. Most routers use 6 or 11 as the default channel so use one of those or, if already using one of them, try the other.
Avoid 1 & 2 as there are too many other wireless devices, including mobile and cordless phones, that use the frequencies of these channels.
Also avoid 12 & 13 because, in some countries, these are illegal. Consequently, some Wireless Network Adapters are designed not to connect on 12 and 13.
