G550 causes DLink router to reboot every 10 seconds

[EarlGrey]

I have a new Lenovo G550, running Vista Home Premium 64-bit and a new DLink WBR-1310 wireless router. Each time the laptop connects to the router through either a wireless connection or a LAN cable connection the router crashes. Then the router rebooys, establishes a connection with the laptop, communication starts and the router crashes again. The cycle continues until I disconnect the laptop. The crash-reboot-crash cycle takes about 10 seconds.

I tested a different router. A TrendNet TEW-432BRP router. The same thing happens. The router crashes as soon as the laptop is able to communicate with the router.

I've taken the laptop to work where I used Microsoft Windows Update and Lenovo Update to ensure that all drivers on the laptop are updated. The only S/W on the laptop is Microsoft Office Pro 2007 and AVG-free (anti-virus) + the S/W that comes with the G550.

At work, the laptop does not crash the router. But at work it does not connect directly to the router. Instead it is connected by LAN cable through a Vonage VOIP system. Meaning the laptop is connected by a LAN cable to the Vonage VOIP unit. And the Vonage unit is connected by a LAN cable to the router.

I also tested the laptop at a couple of public and hotel wireless connections. The laptop is able to connect to these public wireless systems without causing them to crash.

Back at home, the DLink and TrendNet routers work OK with older computers running Windows XP Pro and Windows Vista Home Basic. The DLink also has the latest firmware. WBR-1310 H/W: B1, firmware 2.02.

AVG does not report any viruses and the AVG log file contains no record of finding one in the past.

The router has no custom settings. It is configured with factory defaults. The laptop's network connections (for the LAN and wireless connections) have no custom settings. The laptop's network connections are configured to obtain IP address and DNS server addresses automatically.

My theory about the problem = something in the communication between the laptop & router crashes the router. Perhaps there is something in Windows Vista Home Premium 64-bit. Perhaps something in the Lenovo S/W.

I am looking for help.

Thank you.

At last, I found somebody with the same issue.

At home, I have trendnet router and G550 connects fine but right now at my sis place,

it just keeps rebooting the dlink modem all the time on wireless. Even if I connect it to

the router by ethernet, it wont recognize it. All other machines connect fine.

What can you tell me about the S/W on your laptop, the laptop's configuration and what debugging you have done?

I ran into this with a Dlink EBR-2310. Crashed the router whether the laptop was connected directly to the router or via Wifi (a WAP plugged into the router).  Replace the Dlink with a Linksys WRTP54G.  No more problems.

Same problem with dLink wbr 2310 and a G550. This fixed it.

Disable the IP Helper service:

1. Hold the Windows key and type R, enter "services.msc" (without the quotes) and press Enter
2. Scroll down to the IP Helper service, right click on it and select Properties
3. In the dropdown box that says "Automatic" or "Manual", set it to Disabled and then click on "Apply"
4. Then click on "Stop" to stop the service from running in the current session
5. Click OK to exit the dialog



Disable IPv6:

1. Hold the Windows key and type R, enter "ncpa.cpl" (without the quotes) and press Enter
2. Right click on each network connection and select "Properties"
3. Remove the checkmark from the box next to "Internet Protocol Version 6 (TCP/IPv6)
4. Click OK to exit the dialog

NOTE: You should do this for each network connection.

I tried your suggestions - disabling TCP6 on both the WiFi and LAN network connections + disabling the IP Helper service. This did not solve the problem. My G550 continues to cause either router to crash / reboot every time it establishes a conenction with the router.

I am facing the same problem on the Ideapad Y 550.  Not able to connect to the DLINK 1310.  Tried both the suggestions of diabling IP Helper and disabling IPV6 on all adapters

Please help,

I had this problem too.  Specifically a Dlink router (WBR-1310) and a Lenovo laptop (Y530) running Vista Home (32-bit).  It would show that my laptop connected to the network, then a few seconds later the connection would be down and it would continuously connect/disconnect.  My other system that was connected just fine through the router (running Windows 7) would get kicked off the network.  Connecting the Vista laptop directly to the cable modem, though, would work just fine.

Found this post, and it worked for me.  http://www.justanswer.com/questions/1wau3-bought-lenovo-laptop-y430

Just go into your Dlink configuration's Advanced tab, then the Advanced Network sub-tab.  Uncheck the UPnP (universal plug and play), save the settings, and let the router reboot.

Now both my systems (Vista and Windows 7) are happy and connected through the router.
