DIR 625 wireless interference

I recently bought a D-Link DIR 625 and finished setting it up a few hours ago. After it was all working, I tried using a computer that was a few feet away from it. The mouse and keyboard are both wireless and after setting up the new wireless router, they became VERY unresponsive.

Is there any way to adjust the frequency a little on either one, to stop the interference? Or is there some other solution? I've tried looking around but I can't seem to find anything.

Thanks for the help

 

Without knowing anything about your wi-fi or bluetooth management utilities, I don't know what's available; however, you should check to see if you have the ability to constrain how much of the 2.4GHz frequency (which is actually an 83MHz wide band of frequencies, centered around 2.4GHz) your bluetooth devices are allowed to hop around in. If you can, then try preventing your bluetooth devices from using either the first 22MHz or the last 22MHz within that available frequency band, and then set your router to use either channel 1 (which corresponds to the first 22MHz of the 83MHz-wide band around 2.4GHz), or channel 11 (which corresponds to the last, or top, 22MHz of that band). If that's possible, that should prevent the two signals from stepping all over each other.

The basic problem, as described in this 2002 whitepaper from _HP on Wi-Fi™ and Bluetooth™ - Interference Issues, is that both protocols operate on the same set of frequencies, and both are designed to avoid collisions by restricting their output when they detect collisions occuring. The practical result is that bluetooth will slow down like molasses in the face of a strong wi-fi signal. The interference occurs because wi-fi is allowed to use 22MHz-wide slices of the 83MHz band centered on 2.4GHz, which allows 11 channels, but only 3 channels that do not overlap at all with each other. Bluetooth, on the other hand, is permitted to hop around between 79 different 1MHz-wide slices of that same 83MHz wide band.

Part of your problem might also be caused if you've configured your router to select its channel automatically, and to shift channels when it detects interference on one channel. In this instance, you might have both bluetooth and wi-fi hitting each other's signals, switching channels, and hitting each other again, and switching again, and.... So, even if you can't restrict the range of frequencies over which bluetooth can hop, if you set your router to operate on just one channel - whichever channel is the least crowded in your local wi-fi neighborhood, then at least the router won't be switching channels each time it collides with the bluetooth as well as having the bluetooth switch each time it collides with the router's signal. That, in and of itself, might give you some improvement.

 

Ya, sorry about any lack of info. I don't know much when it comes to wireless and bluetooth. After browsing the needlessly complicated router interface I think I turned off the automatic channel selection and gave it a static channel. That was a surprisingly simple solution. I feel kind of stupid now lol
