So I have a "VTech" DECT 6.0 cordless phone system - single-base/single-handset. It sits about.... 5-6 feet away from my DIR-655 (no direct LoS). What's interesting (and annoying) is that whenever I pick up the handset and turn it on... my WLAN resets. You know, the "wireless XXX disconnected: received deauthentication" message.

Now I did some research on DECT 6.0 and found out that it's supposed to be wi-fi friendly AND run at 1.9GHz. Now why would a device running at THAT frequency interfere with my 2.4GHz WLAN?

(I also found out that there are a lot of potential health issues with DECT since it's basically a miniature cellphone tower in your house, but that's another issue)

I've already started scouring my local stores for a decent 5.8GHz cordless system, hopefully that one won't screw around with my WLAN :/

I've been using a 5.8 phone ever since I setup my wireless network 4 or 5 years ago and have never had an issue with the phone interfering with the router.  You will just have to be careful if you change routers in the future as some of the newer ones are operating on both the 5.8 and 2.4 band.

5.8 here aswell, no probs

we design our routers to be compliant with cordless phones for emergencies.

Perhaps the phone is not so 'polite', low quality or it has a defect ('production inconsistency'). Although transmitting on another band, it might produce some spikes into other frequencies. Ask a tech guy to get some equipment to measure it.
