computer keeps disconnecting and reconnectin to wireless every 2secs

i don't have any mDNSresponder.exe active in processes.. or bonjour in services...

any more ideas on what to do? i also posted the ipconfig previously. thanks!!

Have you tried deleting the wireless profile and then recreating it?

What kind of security are you using for that wireless connection?

if you mean the profile on the d-link software, yes, recreated it like 5 times. I'm using WPA2 with EAS.

ok, i bought another adapter and internet now works; thing is, internet is not running continuously...it like stops for a few second every minute or so...this isn't so bad while browsing but when playing an online game it ruins everything. i'm suspecting the internet connection itself, but how can i test it?

If it's the connection itself then it would affect your other wireless devices as well (which I think you said function okay).

What results do you get with this:

Speedtest.net - The Global Broadband Speed Test

How far away is your computer from the access point?

Ok so it's pretty weird on speedtest. The download speed is spiking during the test, from an average of 5Mbs to ~20Mbs, sometimes 0Mbs. On one test I got 20Mbs/6Mbs, on another got 3/3. 5 minutes later something in between. Ping varies from 10 to 40...

Computer is like 6-7m away from router, signal through 2 walls.

Not really sure what I'm supposed to see from Xirrus.

Side question: The new adapter I got is Dualband, and it says it's connected to my router on channels 11 and 7, but my router is only sending on channel 11, is there a problem? Channel 6 is another wifi, that's why I'm concerned.

To be honest I don't know enough to help on dual band wireless. Very little practical experience. But I'd have to say it sounds very odd to see your adapter connected via 2 channels yet your router is broadcasting only 1 channel. So I'm guessing you may have a valid concern considering how channels overlap adjacent channels (like you might actually be connected to two access points and bouncing back and forth). See this:

https://en.wikipedia.org/wiki/IEEE_802.11

Use that app I linked to. Experiment with it a little and you might be able to identify what's happening and maybe rectify the problem.

It would be helpful to know the router and adapter make/model, and what wireless protocols you're using (802.11b/g/n/ac) and broadcast mode/encryption settings.

I know a someone here that has quite a bit of experience with wireless issues. I'll contact them with a link to this thread. In the meantime get that other info and post it here for us.

Sorry for late response, I was out most of the weekend. So here it goes:

Router is Zyxel NBG-419N, using 802.11b/g/n and security mode is WPA2-PSK with encryption AES-CCMP. The router firewall is off, hoping the internet works better like that. I was using MAC filter before the router reset, but haven't reconfigured it yet.

Adapter is Netgear N900 Dual Band USB Adapter WNDA4100.

Now about chev65's reply: changed to 20Mhz only and yea, adapter says it's connected only to channel 11 now. Disabled Virtual miniport adaptor and uninstalled d-link software (which I've done before installing netgear actually). There was no other wireless profile to delete.

I was checking the log again, and I get this every ~30s:

NBG-419N local6.info upnpd[3498]: AddPortMap: IP: 192.168.1.39 Prot: UDP Port: 52063 App: Teredo

Showing to upnpd[3499] instead of 3498 every other time. What does it mean? And apparently it's not only to my computer (the 192.168.1.39 being mine), it also happens to a laptop (with 1.34).

I'll give it a try for a day with the current settings and see if it's better and reply after that. Thanks!
