The cable modem/router will now select DFS frequencies if it detects congestion on your non-DFS bands, and if a DFS frequency is not in use by a nearby radar installation. From the pull-down menu for 802.11h (DFS), select Enabled and then click Save.You should see the following screen (the DFS entry is circled for clarity): Select Advanced Pages in the upper right-hand corner of the landing page.To enable DFS on current Motorola cable modem/router products, follow these steps: Motorola products with DFS include the MG7550 and MG7540, and we will be adding DFS to a number of other products including the MT7711 and MG7700.

If that’s the case, it’s probably best not to use DFS. You can anticipate this issue if you use WiFi Analyzer to see whether ALL 5 GHz channels are sometimes busy, even the DFS channels. Routers with DFS turned on may have problems if the routers are too near one of these installations. DFS channels are also used by radar systems at airports, weather stations, and other government radar installations. Note that routers with DFS capability typically let you switch that capability on or off. The reason is that DFS unlocks many WiFi channels that aren’t normally used by your neighbors so operating on a DFS channel should result in less WiFi interference and better WiFi performance.

If all your non-DFS channels have significant WiFi noise from your neighbors in some spots in your home, you should consider DFS. WiFi Analyzer lets you check the strength of the WiFi channels as you walk through your home. When you’re using 20 MHz channels, there are 30 DFS channels and 15 non-DFS channels. WiFi Analyzer lets you get good information about each 5 GHz WiFi channel. Here’s a link to information about WiFi Analyzer:

If it’s more than three or four and they are close by, you may want DFS.Īn even better way to check is to download a free app called WiFi Analyzer that’s available for Android phones, but unfortunately not for iPhones at this time. You can see how many networks are within range of your phone. One way to do a quick check is to go to the WiFi settings section of your smartphone, and first make sure that WiFi is On. Those signals create WiFi energy that can interfere with your router or cable modem/router. If you live in an apartment or condominium, your WiFi may be hurt by the WiFi signals coming from your neighbors. WiFi DFS May Be Great For You If You Live In An Apartment or Condo
