Thomson router/access point channel conflict for WIFI printer

[#1]

I have an Epsom WP-4535 connected to my laptop via WIFI through Plusnet Thomson router. Printing works, scanning doesn't. Printer says network working correctly but "A router/access point channel conflict has been detected. Anyone know how I can fix this please?

Hi simonlabrow,
It may be worth either setting your wireless encryption to WPA instead of WPA2 and/or your interface type to 802.11b/g rather than b/g/n

Hi simonlabrow,
1.Type 192.168.1.254 into a browser address bar
2. If prompted enter username: admin
                            Password: CP********* (found under a bar code on the underside of your router)
3. from the left menu select 'Home Network'
4. In the center, left click 'WLAN PlusnetWireless'. This will take you to a page entitled Wireless Access Point.
5. At the top right of the page click on 'Configure'
6. Near the bottom of this page you will see WPA-PSK version. Use the drop down arrow to select WPA - at the top of the page you will also see 'interface type'. This can be changed in the same way.
7. Once you've made your changes click apply.
Hope that helps.
Jojo
