Why am I regularly kicked out of my wireless inter

Thanks to posters to this forum, who assisted me in earlier threads, I now have an Internet wireless network running in my apartment :)

I noticed today that I am kicked out of the wireless connection every 10 minutes or so. I then have to log back in. I set up WEP encryption today - will that have anything to do with this?

You might have some other device that cycles through every 10 minutes which is blanketing the signal band temporarily.

What kind of signal strength do you have?

A common problem is either a microwave (which wouldnt have this regularity), or a cordless 2.4 GHz phone.  If you go into your router's config screen you should be able to change the channel (from 1-6 or so).  Its probably on 3 or 4 (it seems that everything is).  Adjust the channel and see if that doesn't stop the boot.

Running XP?  Here's how I have mine set up.  I had the dropped connections problem for a while too.

Get the latest service packs.  There was an issue with their zero config mgt stuff.

Go to the "wireless networks" tab.

Under "preferred networks" hit "configure".  "data encryption" is checked.  "Network Authentication" is unchecked.  I manually entered my key.  The "Enable IEEE authentication" box under the advanced tab is unchecked.

Close that down, reopen it, make sure under "available networks" that the settings are correct.

What do you mean by "kicked out"?  Is it dropping your idle connections (like in SecureCRT), or something else? 

A lot of those little routers drop idle TCP connections very frequently.  Some applications will let you send a keep-alive every few minutes to prevent that, but you might try googling for "idle timeout" and your router model number for more ideas.

the closest access points needs to ping to  your machine constatly, maybe your firewall is set at such a high level that it does not let the access point ping to your machine!

Isn't it laughable that the wireless networking solutions choose to run on same bands as your microwave and phone.  I know of someone who had to go get a new cordless phone to fix his problem.  The 2.4ghz phone caused problems until it was replaced.

You'd think the Linksys et al would put a tad more forethought into their devices.

I think they're severely limited in the U.S. by what the FCC lets them use, since just about all usable frequencies are taken by some device or another.

Not really. The spectrum they use is heavily regulated.

They have 5GHz devices. It's called 802.11a. No interference. The problem is, the range sucks, and the penetration sucks. The other two choices, 900MHz and 2.4GHz, are both chock full of noisy devices. That's why 802.11b/g allow you to choose channels, so you can opt to try and tweak things.

They can't just pick a frequency out of thin air. That stuff is highly regulated.

I had similar experience for a while with my wireless net. Moved my WAP to a different spot in the office and now I've got no problems. Check out what happens if you're in direct line of sight for a half hour. If the problem goes away, you might try to find a better spot for the WAP.

“They have 5GHz devices. It's called 802.11a. No interference.”

Phones are slowly moving to the 5GHz band as well.

The reason that so many conflicting devices use the band is that it is the band that is available for unlicensed use.

Phones are very slowly moving to 5 GHz. However, if you look, the 5GHz band has much tighter specifications on allowable interference and how it must be handled.

I have also experience problems with Win XP WEP encryption settings.  XP seems to decide to forget its WEP key from time to time.  I have no idea why.  More recently I put the XP machine on a cat 5 cable so I don't have to worry about this any longer.  My "loss of key" problem only occured every few days, not every 10 minutes...

> Phones are very slowly moving to 5 GHz

So wirless networks can probably move down into 900mhz in a few years when the marketing hype is such that no more 900mhz phones exist....

The only phone I have in my pad is cellular.  Problem solved.
