Lenovo laptop REFUSES to stay connected to internet(wifi AND lan)

HI all, I have a lenovo laptop that is almost exactly a year old and it WILL NOT stay connected to the internet neither by wifi nor LAN. It will connect sometimes for 10 mins, sometimes for ten seconds. I can turn the computer off, restart it, close all other programs, diagnose connection, disable and restart adapters, nothing works for very long. I dont believe it is the internet as my Xbox, my desktop and my phone all connect fine through both wireless and wired connections. There are also two other laptops on the house that connect just fine (not windows 7 machines tho) my desktop is also windows 7 and sporadically has this problem as well. I have tried going to barnes and noble and starbucks to try different internet and still the same thing happens. Very Frustrating, please help if you can

Hello and welcome heavy mate have you checked the driver for the adaptor in Device Manager?

@ICit2LOL, I checked the device drivers and the Broadcom 802.11n Network Adapter is up to date, but the wireless controller did take an update. Restarted the laptop and still having the same issue.

You could try flushing the DNS cache and see if that helps.

The FlushDNS.bat file in Network Posting Tips makes it easy.

DNS I dont think is the problem, because I cant connect to my desktop which is on the same network. But, cleared the cache anyway and still no change in behavior

Sounds obvious but have you tried a new LAN cable?

Hum try a scannow heavy > in command prompt run as admin type sfc /scannow (there is a space between the sfc and the /) and hit enter.

Shouldn't take long and is just one less thing to check out. (mine is blue / white of choice yours probably black & white different font too)

Slight hangup with the scannow approach ICit...I am logged in as an administrator on the laptop (it even says C:\Users\Adminstrator2) but it says I "need to be an administrator running a console session to use the sfc utility"...

Did you right click on CMD.EXE and click "Run as administrator" to open the CMD console window?
