How do I change the wireless channel on a CISCO 1811W (MPC8500) router? Currently it is channel 10 and I prefer to change it to channel 1 to reduce interference with microwave oven. I have already replaced the standard antenna with 7dBi high gain antenna.
Out of 12 wireless clients about 3 are being dropped whenever microwave oven is turned on. These clients have Linksys WMP54G Wireless G PCI adapters. Other client computers are notebooks with builtin wireless adapters and desktops with Belkin, TRENDnet, or Motorola Wireless PCI or USB adapters.
All computers are within about 60'-80' radius from the CISCO wireless router and are about 20' away from the microwave oven. Any suggestions?
You need to "telnet" to the device using the windows command prompt or a similar terminal emulator (putty, etc.). So instead of using your browser and going to the 10.10.10.1 address you would type "telnet 10.10.10.1" into the command prompt or terminal emulator. From there you would log in to the router with your credentials (should be the same as you use for SDM). Then once you are in the router prompt (router>) you would type "enable" and apply the specific enable password to get to the Privilege EXEC or enable prompt (router#). From there the instructions you have (likely from page 38 of this document).
If you are not familiar with CLI or Command Line Interface then you need to be very careful with what you do so as not to misconfigure something else. I would recommend reading through a Cisco IOS command reference guide (based on the version of IOS your router is running) first and also make sure when you make changes to apply it to memory with a "write mem" command from the "router#" prompt when you are sure you have made the change you want and need to save it.
If you are not very familiar with CLI then I would HIGHLY recommend some initial self-study and reading prior to attempting anything in CLI on a "live" router that's in production. The consequences could be serious if mistakes are made.
Best of luck!
