I'm pretty sure this has to do with the DIR-655 router as I have never had any issue with this on my linksys router.  I have a laptop that I use windows remote desktop to access from a desktop, this laptop is wireless g, intel wireless chip.  My desktop that I use to access my laptop using windows remote desktop is connected using cable.  I can usually connect just fine to the laptop but if I walk away and let them set say 10 to 30 minutes then when I come back to remote to laptop it has lost its connection and cannot connect back until I log back into the laptop from the laptop then it will re-connect the wireless session.  I am running the beta 1.22 5 firmware for the DIR-655 router.  This beta firmware seems to be better than the 1.21 version.

Here are the logs to show for some reason it is receiving an error with Authentication.  Some info removed in between but is all the same information but would not all fit in this message.

Which Intel adapter is it specifically?

Which driver version are you using?

Wireless settings?  List them out please.

What OS?

[lotacus]

a few possibilities, and they have to do with the laptop.

1: Your nic is set to sleep. This can be disabled at the driver level.

2: Your Remote Desktop session is set to disconnect after a certain time-out period.

3: Your laptop is going in a low power state. Check the power saving settings.

Update your stuff.  See if that will fix it.  I figured you were probably using older software.

http://downloadcenter.intel.com/T8Clearance.aspx?sType=&agr=Y&ProductID=1847&DwnldID=17231&url=/17231/eng/12.2.0.0_x32.exe&PrdMap=&strOSs=44&OSFullName=Windows*%20XP%20Professional&lang=eng

Drivers have a small update, but see what happens.

This Intel chipset does not really belong to the all time favotites....does not solve you issue, but it might be a consideration when buying an 'N' USB NIC 

[rcschaff]

Last night I decided to try some things, because I realized when I switched over to the dlink router I also changed the security I was using on wireless which I went from WEP to WPA, which I didn't think would make a difference but I was wrong.  I pulled out my linksys router and changed the security to WPA and tried that and found that it indeed also disconnected after a period of time, possibly due to something go to low level power on the laptop.  After that I changed it back to WEP and re-tried and found that it would stay connected.  So then I went to my dlink router and configured that to WEP and found it also stayed connected.  This was kinda of good find, at least it wasn't the dlink routers fault. 

Going back to my laptop I'm kinda of stuck on the software version used for the wireless as this is used for work and they have profiles that are locked down and installing the new version will remove those and prevent me from connecting to work.  I did find the newer version at work and installed that version and I'm currently testing it out, and will let you know if this fixed my problem.

Keep in mind you can't get N speed when WEP is enabled.  The best you'll get is G / 54mbit.  It's due to a restriction with the 802.11 draft-n spec.

However, you didn't mention that you're using any N devices in your network, only the ABG Intel WNIC so if you're only using WEP as a deterrent to keep people off your network -- cause let's face it, WEP can be cracked in less than 5 minutes -- then make sure you change you wireless mode to "Mixed 802.11g and 802.11b only" for better performance.

When you want to go to N, it's best to skip right over WPA & TKIP security and enable WPA2/AES only.  The latter has the best performance profile on the DIR-655.

[rcschaff]

I am using WPA2 with AES, that was my main go was to switch over to that security setup so I can run N wireless on my other wireless computer, which I also tested for dropping the signal and it never did, which also started to lead me down the path that it might be my laptop. 

It was just not what I expected since I changed over to the new dlink router and started to have problems.  So like must people I was blaming the new device installed.

I do get 300mbps from my wireless N computer, with my current configuration.

So far my laptop is running without any disconnects.

I have the same issue with my Lenovo Thinkpad T61 (same log entries as the first post).  Whenever I do remote desktop from office to home, it will work for about 10 minutes and then the wireless connection will drop and never able to reconnect again.  I am using the Thinkvantage Access Connection util to manage my wireless profile and I found out today that by disabling "Disconnect from network and power off any wireless radio associated with this profile when switching to a different location", the problem goes away.  I am not sure why it works because I used to have that option turned on for over a year with my old Linksys (but only a 11g router).  Maybe it is because of switching to 11n, or maybe a newer version of the util behaves differently.  For whatever it's worth, those who are using Thinkvantage Access Connection to manage their wireless profile may want to give it a try.
