Dell Inspiron 5520 laptop unable to connect to internet via Wifi

OMG I am having the exact same issue, I only bought my laptop 2 weeks ago (around 5th August 2012 in Dubai, UAE) and I was able to connect to wifi and use internet until few only 4 or 5 days back it stopped working.  It is connected with the wireless router, but not to the internet.  There are other computers in the wireless network that have no problem connecting to the internet, so I know my router and DSL modem are functioning properly.  When I run diagnostic (troubleshoot) it says Problem Found: "The DNS server isn't responding" I dont know what it means?

In "Network and Sharing Center" at the left bottom there are few options, I clicked on "Intel PROSet/Wireless Tools, a pop up windows opens and it has a "Diagnostics" section, there are few options, I clicked on Diagnostic and there is another pop window opens "Manual Diagnostic Tool" and it says "run tests" which i clicked and here are the results:

Hardware Test                Pass    Wireless Hardware is enabled

Driver Test                       Pass     Driver is loaded. Net wNs64 Version 15.0.0.75

I have windows 7 and McAfee pre-Installed.  please can you help me?

Hi Swapnajan MC!

Thanks for the valued information and feed back. I did try the step you told me i.e. system restore. to a automatic restore point something and a  recommended date (recommended in that box that appeared in system restore) it was August 19, 2012. and after restarting my laptop the internet has started to work (via wifi since i only tried wifi so far) and I am really happy about it. And really really appreciate your help.

I now just have updated McAfee as you mentioned and now will be updating windows 7 too in a minute. and I hope after these updates my internet will continue to work :)

Thanks again

Hi guys. sounds like we're all having the same issue.

Have only DELL machines in the office and only having trouble finding decent wireless connectivity with the two 5520s I purchased recently. The rest work fine.

I virtually have to be on top of a wireless AP to connect with them.

here is an image of DELL inspiron 5520 (left) running next to older DELL inspiron 5110 (right). both machines running the same version of Metageek inssider to monitor wireless strength at the same location. (approx. 12m from wireless AP).

5110 (right) shows full signal on wireless icon and -50dBm on inssider while 5520 shows one or two bars on the wireless icon and -80dBm on inssider (and does not pick up the second wireless AP at all).

.

Have tried all suggestions above and contacted DELL support. they will be sending out an engineer to investigate.

will keep all posted.

dear gent's

i have new laptop dell 5520 the wifi for network is cutting after 10 menutes and give me massege the access limited and i  returned back to conecting and after 10 menutes the wifi cutting but when conecting the modem cable the internet working probably

please help to desolve this problem

Update on the ongoing problem with 5520:

It sounds like I am experiencing a slightly different problem than perfect_prognosis - just permanently poor signal despite updates/ driver changes /dell helpdesk fiddling etc.

DELL sent out an engineer (after taking 2 weeks to source replacement wireless cards). The DELL wireless cards were replaced with intel cards (according to engineer the same card running on the 5110 in the picture above) - with no improvement.

Engineer suspected that the 5520 wireless aerial (located behind the screen) is poor/defective. unfortunately, there are no spare parts in my part of the world to fix this within the next month or so...

I am now making arrangements with DELL to send the machines back for a refund.

I have the same problem bro. The first day i bought this computer i couldnt connect to the internet through wifi, Contacted dell support, i hope they will solve this problem

I am also having the same problem but it didn't work for me, now i have completely erased windows 7 and installed windows 8 but the problem still persists.

thanks
