I have an Acer Aspire 7552G laptop running Windows 7 x64 that is having problems with connecting to the internet.
I started to notice the wireless and LAN connections becoming very weak, web pages would load slower, data would take longer to download, etc. This lasted for a couple weeks. As of now, I cannot get any signal, neither wireless nor LAN.
I normally use Google Chrome but have tried to connect through multiple browsers.
I have tried updating the wireless/ethernet drivers, and I have also tried uninstalling them all together and reinstalling them. Both to no avail. I have no idea how to resolve this issue and am hoping the tech pros here can help me out!
How are you measureing the stregth of the ethernet connection?
Who is your ISP ?. . What Brand and Model is the Modem and Router?
Lets take a peek at your network environment:
First:
Power Cycle everything . . Turn off the Modem, router and all pc's . . turn on the Modem and wait a few minutes for the lights to stabilize . . then turn on the router, then one pc at a time. See if you connect to the internet.
Then:
Remove all the stored wireless network profiles and search for the network again.
Then: check your browser's settings, remove any proxy settings if foundhere's how.
Then:
with the pc connected to the router, Click on Start . . Run . . type CMD
At the > prompt type type the following command: IPCONFIG /ALL
Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.
Right click in the command window and choose Select All, then hit Enter. Come back here and Paste the results in a message.
If you are on a machine with no network connection, use a floppy, USB drive, or a CD-R disk to transfer a text file with the information to allow pasting it here.
then please Download and run this Xirrus Wi-Fi Inspector, click the Networks link on the upper left and paste a screen shot of that screen here. Note that this application requires NET Framework to run. If you get an error about a missing function, download and install NET Framework.
To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.[/COLOR
I measured relative strength of the signal. Currently I cannot load any web pages on the laptop with the problem while I can connect to the same signal from any other device and it will work perfectly.
I am not sure of the ISP and brand of the modem as I am connecting to the internet provided by my university's residential life offices.
No I have not asked the university tech if they are having problems. Like I previously mentioned, the connection is not the problem because I can use it with any other device. It is only on this laptop that I cannot get signal.
I did not think it necessary to ask my university's tech department because this problem is isolated only for this one laptop. I can connect to RESNET-MATTHEWS (the preferred signal in my area) with no problem on my netbook, cellphone, and ps3.
In the elevated command prompt type ipconfig /release and press enter. the IP address should change to 0.0.0.0 now type ipconfig /flushdns and press enter. Now type ipconfig /renew. You should get a new IP address.
You can also try pinging Ucsd.edu (ex) type ping 132.239.180.101 or ping ucsd.edu.
Hi, the netsh commands have to be run from an elevated cmd prompt. Go to start, search and type:- cmd, right click on the returned cmd.exe and select "run as administrator", make sure you are disconnected from the internet, at the prompt type:- (copy paste)
Code:
netsh int ip reset && netsh winsock reset
(press enter)
Next clear your ARP cache same deal cmd as admin type:-
Code:
netsh interface ip delete arpcache
(press enter)
If prompted to restart computer do so.
Next cmd as admin at the prompt :-
Code:
netsh int tcp show global> 0 & notepad 0
(press enter)
post the notepad outcome here. Any improvment? I would also talk to the Uni IT they may have restricted you for some reason...
