Satellite L650/1MC - WiFi and LAN connection keep dropping out
Posted: 13-May-2012 20:17

In the last couple of weeks my wifi connection has regularly dropped - only a reboot fixes the issue. As this was becoming so frequent (and annoying) I went back to using an ethernet cable which worked OK for a few days, but tthat hen started to do the same thing - no internet connection.

I should point out that my other wifi enabled kit (android tablet and android phone) both continue to connect to the internet etc via wifi even when the laptop connection has dropped. This leads me to suspect that the problem is laptop related rather than router etc related. The laptop is rarely used on battery so I don't believe power management to be a problem.

I have a Satellite L650/1MC running W7 64bit. I have made no changes to my system recently which may have resulted in this problem - everything worked just fine up until a couple of weeks ago.

I have checked for updated firmware on my router in case that was the issue - its not.

Any suggestions to correct this annoying issue would be welcome!

Did you try to reboot the router?
Do this… since the both connections (LAN and WLan) keeps dropping, I believe that the router is the problem.
Ok, the both other devices running android seems to work properly but the point is that router shares the IP addresses automatically and possibly the IP address cannot be assigned properly.

At the other hand you can check the WLan and LAN TCP/IP protocol settings.
Uninstall the TCP/IP v6 and use only the TCP/IP v4 for WLan and LAN.

Ensure also that your security programs (firewalls & anti virus software) don’t affect the internet connection.

Hi MasterG
Thanks for your input. Yes, I have rebooted the router (both the cable router and the wireless router) a number of times. The problem just keeps recurring.

The security programmes do not affect the internet - as I said in my original posting, everything was fine a couple of weeks ago, and nothing has been changed since that time.

How do you uninstall the the IPv6 protocol?

How do you uninstall the the IPv6 protocol?

Right click on the network icon and select Open the Network and Sharing Center.
In the new window, select "Change adapter settings".
In the Network Connections window, select the LAN or WLan card and click right to get Properties
In the connection property page, uncheck the box for "Internet Protocol Version 6 (TCP/IPv6)". (do this for Wlan and LAN)

Close all the windows and reboot your system.

Hi
I did as suggested - disabled IPv6 on both wired and wireless. Rebooted. All ok .......... for about an hour and a half! Then problem recurred, had to reboot again to get back online.

Thanks for your input though.

I read about WLan disconnection issues in many different forums…in most cases the WLan issue happens due to old WLan drivers or wrong settings in power management.
But I’m surprised reading here that you have disconnection issue using both cards: Wlan and LAN.
I think there it can be a problem either with router or your system.

In your firs message above, you said that router firmware and settings has been checked and your other devices connected to the home wlan work properly…
This would mean that something is wrong with the system.

It was a good idea to remove the TCP/IPv6 and using only the v4 but since this did not solve your issue I think you should test the notebook with factory settings…of course this is ridiculous workaround only to test if the disconnection issue would be still available but to be honest it’s a fast procedure to recover the notebook and maybe its helps you to sort out this issue.

Hi
Thanks for your input. I took the laptop into work today to see what happened when it was connected to our wifi - would it disconnect. Nope, stayed connected all day, no problems at all. Clearly the issue is not with the laptop itself.

As I said in my original posting, connecting gave no issues until about 2 weeks ago and I had not changed anything prior to the problem starting - I don't "tweak" things such as network/router etc settings - never had any need to once the wifi was up and running as needed.

I will try connecting direct to the cable modem via ethernet cable - and see what happens then.
