The previous answers get you to the point where you can log into your router using the IP address of the default gateway. You will, of course, need the proper credentials (username/password). What you want to do is change the wireless channel. Most modern routers/gateways default to "auto," which means they can change channels at will. I prefer to fix my routers to a specific channel, based on some analysis. For this, I use an app called WiFi Analyzer, which is a free download from the Google Store. If you have an Apple device you're out-of-luck, as Apple will not allow your phone to determine the signal strength of nearby WiFi devices. The WiFi Analyzer app provides various representations of the signal strength of all channels on your router. Simply choose the best channel and set your router to use that channel.

The airport routers have built in antennas and external antennas cannot be attached. For wider range, place the router high up and away from glass, metal, and stone. Try changing wireless channels to lessen interference.

You change the channel in the router's wireless setting.
This does not give you a stronger signal BUT you can select a different channel so you do not get interference with other wireless routers in your area that are broadcasting on the same channel.

Please check the router page and change the channel to 11

Connect to the router by typing
http://www.routerlogin.net in the address bar of a browser.
if it asks for the id and password enter
id = admin

go to Wireless Settings and Change the Channel using the drop down box. Save the settings.

Remember it takes two to tango, so the issue may just as well be in the iMac as in the Zoom X6... Regardless of that, I had the same problem (PC works fine, iMac and PC both get flaky when the iMac is powered up). Zoom tech support suggested trying RF channels 1, 6, or 11. The router was using channel 10, changing to channel 11 calmed things down. Zoom said there wasn't anything magic in those numbers, but their testing showed those channels worked best with the Apple products.

Try to change the channel and the SSID (wireless name) on the router's wireless configuration.
