Netgear Dgn2000 wireless-n router

Specs: Windows Vista
I have a Netgear Wireless-N router and for some reason it seems to lose the wireless connection every 40 mins or so. I will then have to reconnect and retry and sometimes i will even have to reboot the router for it to work again. When i am connected with the ethernet cable it works fine for weeks. Has anyone had this problem with the dgn2000 router.

What type of Internet connection (DSL, Cable)?

Is the router firmware up to date?

That looks like a 2.4 Ghz WiFi router, Y or N?

Do you have also have 2.4 Ghz wireless phones?

Are you using wireless encryption WEP/WPA?

Is the router dumping the connection or is Vista dumping the

Are you on the latest Service Pack for Vista?

It could be your wireless card in your Vista machine too with an issue.

Other WiFi PCs having issues too?

Just another stupid saying...

The internet connection is DSL

Just updated the firmware and the problem is still present

The router is a 2.4ghz

I have a siemens gigaset Al140, the manual says it is a 2.4ghz

Security is set to WPA-PSK (Wi-Fi Protected Access Pre-Shared Key)

It seems to be the router that dumps the connection. I have 3 computers on the wireless network (win7 wista home & xp home) and they all lose the connection at once. The desktop is connected through the LAN and seems to hold the connection

My buddy has the same router and is experiencing the same problem. They also have siemens gigaset units.

I suspect that either the DHCP is crashing or there could be a conflict between the portable phones and the router. I have setup static IP addresses on the computers and im waiting to see if the wireless holds.

Interesting that you & your buddy have the same equipment,
and the same problems.

You said the LAN connected PC (via Ethernet cable I
assume) stays connected. Test to see if it stays connected to
the Internet and not just the router.

Interent drops repeatedly (which may not be your issue):

Improving Wireless Range: Overview:

I'd make sure all your settings on the router are correct,
enable logging too for better troubleshooting.

Testing the WiFi router w/o the wireless phones powered on for a day or two may be a good test.

I would also try changing the WiFi channel on the router to 1, 6 or 11. I have seen some 2.4 Ghz routers work OK with 2.4 Ghz phones, and I have seen issues with phones. Doesn't happen often, but once or twice I was at a customer site, phone rang, then WiFi on laptop disconnected.

Just another stupid saying...

So far I have mangaged to switch off the Siemens Gigaset for a few days and still no luck, the router still kicked off the wireless users only. So I took time off to monitor the router, i tried the following:-

1. Added Address Reservations for all the wireless devices on the netgear router
2. Changed the wireless security from WPA-PSK to WPA2-PSK
3. Changed the chanel to 'Auto' in wireless settings
4. Changed the mode to 'g only'
5. Updated the keys on all the wireless devices
'the only noticable difference is the speed of the wireless network is noticably slower when copying files over the network'

So far (holding thumbs) i havent had the problem for a day and thats a BIG difference. The router hasnt crashed so far. Will let you know how it goes.

Thanks for all your help so far!!
