| DECT interference?
I've read various places on the internet that the DECT 6.0 phones aren't supposed to be a problem with wireless routers and/or WISP's. That said, unfortunately I got a Panasonic DECT 6.0 phone AND a new wireless ISP (Bell WiMAX) at the same time and have been having problems since.
I have to cycle my modem/radio every so often because I lose connection. I haven't noticed any possible provocateur except tonight. My wife picks up the phone and starts dialing somebody while standing next to me. The wireless router is right behind me. Within a second the connection craps out and I have to cycle my modem again. It'd been a day since I had to cycle it at that point. After screwing around with renewing my ip etc... I finally call up Bell to put in a ticket yet again.
Any suggestions as to the likelyhood of the the DECT system friggin up my actual WiMAX unit or at least it's connection? I don't THINK it's my Belkin G router since when I bypass my router and plug directly into the computer it doesn't seem to make any difference.
A link to a possible problem with the DECT system, if it's verifyable. »discussions.apple.com/thread.jsp···=6444415 |

| DECT purports to not interfere with WiFi and that is supported by fact. Bell WiMAX is NOT WiFi so you don't have a basis for complaint.

| I can't find the frequency of the DECT 6.0 Panasonic I have. I know that my WiMax is uses the 2.4(?)GHz Motorolla OSU and wonder, if the phone is around 1.9GHz (i seem to have read that online somewhere if my memory's right) and my wireless network also uses around 2.4 GHz, could the phone be causing resonance 'echos' when it's being used? There shouldn't be complete spectral interference, but surely having a frequency close to that of the network would cause jitter.
Just thinking out loud. Otherwise I can't figure out why my old 900 mhz panasonic cordless didn't seem to be an issue. I hate having 2 variables (new isp AND new phone system). I suppose I can plug back in my old 900 mhz to seal the deal to see if it's the new phone. |

| said by jnmontario  :I know that my WiMax is uses the 2.4(?)GHz Motorolla OSU... I am quite confident that Bell's WiMAX is not running in the 2.4 ISM unlicensed band.
The first step in mitigating interference is to relocate (as in move apart) the two devices. Even though they use different frequencies, a strong RF field can desensitize the input of a receiver.

| From my experience, DECT doesn't interfere with WiFi as long as the base station and the router are at least a few feet apart, but I have to test some more on that. Thankfully, at my house there are no such interference problems (the DECT stuff is at my former school)...all old 900 MHz cordless phones here, and the WiSP we're using uses 2.4. Noise floor for the router varies as high as -93 db, but is usually -95, so the connection works where it needs to...I wouldn't use a 2.4 GHz phone in conjunction with any WiFi network but previously the school was doing just that, and getting lousy phone performance if I remember correctly... |

After much friggin' around. I think it was the Belkin router. I switched back to my old WRT54G and it seemed to have cleared up the problem. I'll post an update if it no longer works. |

Fredericksburg, TX | Not to gloat, but I've found that Belkin makes lousy routers compated with Linksys. I didn't see your posting about using that router vs. your WRT or I would have said "try the other one!" |

| It's ironic. I switched from my WRT to the belkin when I had ISP issues before. I find it amusing I had to switch back from the WRT when I switched WISPS.
It also turns out that even switching to the WRT I'm still having random slowdowns. Almost always in the early night (8-10 pm or so). Dunno if it's maybe humidity-based? There was no wind last night, but my signal dropped from 3 lights to 2 lights.
Ah, the dangers of living JUST within range of your WISP tower. |

Fredericksburg, TX | On the other hand, WiMax may have the "cell breathing" problem, where high usage means lower ange. Which would explain for the slowdown and signal loss...I know cell breathing happens for CDMA... |

| Interesting! (it happened tonight btw. that's 3 nights in a row between 8 and 10).
What's ange?
I also find it interesting that I have an anti-terrorist army base training facility a degree or two off of my line to the tower. I wonder if somehow they're involved since this slowdown has happened during the day before (the day after I first got it). |

| Maybe they borrowed this from the US Army.
