Windows 7 laptop wifi connecion issue

(1/5) > >>

Hello! I recently moved, and I am experiencing difficulty with wirelessly connecting to the internet on my laptop only. Sometimes when the computer turns on, it will take a minute or two to conect to the network automatically. If I try to connect manually, it usually says something along the lines of "Issues connecting to network". I tried the troubleshooter, and it told me it found problems it couldn't repair. I have run windows repair, as well as complete internet repair, and they did not help. The network also doesn't like to reconnect after going to sleep. It has so far always joined eventually, but I have never had these problems before. It has also disconnected me while I was using it for no appearent reason. I have other mobile devices that connect wirelessly, and they do not appear to have these problems. Does anyone know what causes this, and how to fix it? Plugging the laptop into the modem with an ethernet cable is not an option right now. Thanks in advance!

I've never been a fan of Hibernation as it can hang onto the DHCP IP address it was assigned prior to going to sleep, so when the machine is reawakened, DHCP will  assign it another one which will cause a conflict if different.

Do you have any other wireless devices near the laptop that could disrupt your WiFi signal and how far away is the laptop from the router ?

Drivers can cause connectivity problems,, so update/reinstall the wireless adapter driver.

You can either go to the adapter vendor support site and look for an update (recommended) or go into Device Manager by going Start - type devmgmt.msc and press enter.

Click on View/Show hidden devices then expand Network adapters - right click on the Wireless and select Uninstall - but do not check the box to include software.

You can either click on Action/Scan for hardware changes or reboot for Windows to reinstall the driver.

Sometimes the MS Virtual Miniport can cause problems and that can be turned off with a cmd run from an elevated command prompt, but it will be reinstated when the driver is installed from the vendor support site.

If you don't use a VPN then it isn't needed.

Go Start - type cmd and right click on cmd - select Run as administrator - accept the UAC and enter -

netsh wlan set hostednetwork mode=disallow

exit

The next time it disconnects, can you open a cmd prompt and enter ipconfig /all

Right click in the text area - click on Select all and press enter and then you can right click in the Reply box and select Paste

One other thing to check for the disconnects is to right click on the wireless adapter in Device Manager - click on Properties and under the Power Management tab, uncheck the box for Allow the computer to turn off this device to save power.

I'll answer in order: I use sleep mode not hibernate, and the problem can/does occur during startup. I do not have any other wireless devices "near" it, butI do havs some in the house. I will check for update to the driver, but right now I don't have access to the computer, so that will have to wait a little bit. I'll do it tonight though. As for the miniport thing, I don't use VPN. I'll also change that setting later today when I update/reinstall the network adapter. Any idea what could have cause this? I didn't have problems before. Could the laptop just be partially incompatible with the modem?

Boggin:
I had come across a while ago where there was a compatibility problem between the wireless adapter and the router.

I think it was between TP-Link and a Belkin router but can't remember the TP-Link adapter model.

Drivers are often the cause of connectivity problems where other devices aren't affected, but I'm curious as to what the trouble shooter said it was unable to repair - if it had been the driver then it wouldn't have been able to do anything with that.

If you take note of the time you get a disconnect, Event Viewer may have a time stamped error that relates to it and as the WiFi is usually the last thing to connect on boot up, it may also have something recorded for that as well - it could be listed as a DHCP error.

I'll check the event viewer if/when I get disconnected again. Also the troubleshooter may have detected the fact that I was not plugged into ehernet as an issue, it mentioned something about that. Also, I use driver booster by iobit as my driver updater, although it does limit the driver database unless you have premium. Anyway, it has a tool in it that claims to fix "cannot connect to internet" errors. I ran it while my internet was "down" and it said something like "error has occured cannot fix". Just thought I'd mention that too. Also, Windows Update broke my internet twice trying to update my wireless driver. The first time, about a year or two ago, I was updating it manually. The update failed so I had use system restore to get it working again. I hid the update so it wouldn't auto install. Next time, my wifi just conked out for no reason (about 2 months ago I think) and I found out it had tried to update a "critical" update which was probably my wireless driver again. I found that out because it had automatically made a restore point before it installed (thanks for not failing utterly Microsoft!). Everything worked fine afterwards, and I think I got the driver updated hrouh a different way, but I'm not sure. I only moved a week ago, and it was workig fine before than, so the two aren't necessarily related, but I thouht I should mention that as well.
