Recently changed router & one computer can't connect.
Our last router seemed to be having problems so my roommate got a new one from Time Warner as a replacement. All of our other roommates had no problem at all when reconnecting to the new router. There are 4 of us, but any given time there may only be two of us using the internet....very seldom all 4 are home at the same time. The only computer having a problem happens to be mine and the only machine with Vista on it.

One of my roommates changed the router while I was away from my notebook which was running and connected to the internet at the time he made the switch. I don't know if this was the cause for all my troubles in the last week trying to figure out why I can't get back online, but I had no problems with the other router except for the signal dropping too low even when we were within a couple of feet of it. There were no changes made on my end nor did anyone else have to make any changes to their computers other than connecting with the new password. I often take my netbook with me and have connected to hundreds of other networks without a problem until this recent change. I can still log onto other wireless networks, but just not to our home wireless network .

I can use the Ethernet and connect to the internet just fine, but I can't seem to get passed the Limited Connectivity when connecting thru the wireless connection. The network key has been double and triple checked by myself and others...it is the correct security key. I've tried changing up the security key just to see what would happen and it won't allow me to connect to the network unless I put in the correct key which still limits me to Local connectivity anyway.

I have been searching for a solution to this for over 6 days now. No one seems to have the exact same issue as me which seems odd as there hundreds of somewhat similar issues others are having, but just not 100% identical to my situation.

I've contacted Time Warner & Linksys. Time Warner obviously hires idiots who seem to be just reading automated responses and like to keep you on the phone for 2 straight hours going thru motions even if I've already told them I've tried what they suggest and was unsuccessful in troubleshooting the problem. I still followed through with their requests to no avail and they eventually gave up trying. The router is not under warranty according to Linksys so they just forwarded me some basic troubleshooting links that had me going through all the same crap that I've already been through several times now.

Somebody please help me. At the moment I can't afford to have a tech come over to fix it and I have a paper that will be due by this Thursday that I'm well behind on now thanks to all this. How can changing out a router make for so much of a hassle?

--I have Compaq Presario CQ50 (let's not trash talk my machine, I'm well aware it's not top of the line).
--I'm running Windows Vista Home 32-bit (has to be the worst OS ever created by Microsoft)
--Router is a Linksys E1000
--I've disabled both the AV and firewall in hopes it was those blocking the connection
--I've tried disabling the security encryption on the router and that actually disconnected me completely from the network.
--I've also tried the TCP/IP stack repair with no change after the reboot.

Here's my "ipconfig /all" while being connected to by both Ethernet and the Limited Connectivity via the wireless network.

I hope this will help. Is the DNS server suppose to be socal.rr.com? I've never seen that before in ipconfig....is that Time Warner's server or something because I remember the DNS having numbers when I lived in another part of the city that only had AT&T Broadband available?

Any help that I can get would be greatly appreciated. My teacher may be happier with me if I turn something in without an excuse about my computer problems.

EDIT

just noticed you had an Ethernet connection - so scratch the IT ping other sites - as thats from the ethernet connection and so - you will have the symtoms of the AR5007 - so have a read of that section first

can we see an xirrus screen shot

You are connected to the network and you can Ping other sites

Atheros AR5007 802.11b/g WiFi Adapter
this adapter can give lots of issues - but your symtoms are slightly different

in that you are connected to the router - which is normal the symptoms
BUT you are pinging the internet which is not normal

OK - so quite a few things to try

1)
first firewall / security suite - do you have or ever had a full or a trial security suite - like Norton , mcafee
the symptoms you have are those that show a firewall blocking
often the removal tool will solve the issue -

2) xirrus screen shot - see how below
3) TCP/IP reset - see below
4) AR5007 - list of issues and things to try - see below


------------------------------------------------------------------------
Run Xirrus Wi-Fi Inspector
Download and install

If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.


http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
Direct link to the program is here http://wpc.475a.edgecastcdn.net/0047...etup.1.2.0.exe

{If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}

Then run and install the program - on a wireless enabled PC/Laptop
if you get an error - You need NET Framework installed for the WiFi Inspector to function.

Run the program

A user guide is available here http://www.xirrus.com/Products/Wi-Fi...uide1-2-0.aspx

post a screen shot of the program running - if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information, and also post which network "Adapter Name" (1st column) is yours on the list

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.
Full details are here http://library.techguy.org/wiki/TSG_...g_a_Screenshot

Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better.

If you are using the Mac OS then use http://www.istumbler.net/

Atheros Wireless Adapter - AR5007EG & AR5007
We have recently been seeing a lot of problems with the above adapter over the last few months, mainly concerning WPA and WPA2 encryption and windows Vista.

The adapter gets an IP configuration, and shows as connected, but communication is non-existent or sporadic.

Log into the Router and disable the wireless security and see if you are now able to connect to the internet and surf OK.
--- Please post back here if that
works or does not work.


Here are a number of possible solutions

--- 1) In Device Manager right click on the wireless adapter and "update driver." That apparently has worked for some posters.

--- 2) Download and install the latest wireless driver from your laptop manufacturer's web site support section, as some manufactures, appear to now have a working driver available.
Toshiba - update has worked for some PCs
HP The latest HP Atheros driver dated Sept 2010 has fixed the issue - so check the driver date, However, that does NOT apply to all HPs / Compaqs machines
- the poster did an online scan for driver updates on the HP website here HP Product Detection which resulted in a solution. Solved: Can't connect to internet wirelessly - Atheros AR5007 Wifi through Clear Comm - Tech Support Guy Forums

If you can post the Make and EXACT model of your PC here, along with the windows version you have and we will see if we can find the driver and will post a link as a reply here.

--- 3) On one occasion re-setting the router back to factory default and re-configuring the router settings has resolved the issue

--- 4) A few posters here with the same issue have found that the driver from this site ATHEROS drivers for Microsoft Windows resolved the issue
Threads are here
Solved: Public Network - Access: Local Only (Please help!) - Tech Support Guy Forums
Solved: NetGear WNDR3700 Incompatibilty W/ Atheros AR5700 - Tech Support Guy Forums
Solved: Local connection only when connected to secured wirless - Tech Support Guy Forums
Solved: Unidentified Network - Tech Support Guy Forums
Unidentified Network


I do NOT know anything about the site mentioned ATHEROS drivers for Microsoft Windows However, a number of forum members have now successfully used the site to update the driver

However, if you do decide to try the driver, Please let us know the outcome

Direct link to the drivers are below
You only need to click on the green download button labelled " click to download " and wait, the file will download - you do not need to click on any other buttons to get the download started

AR5007
Vista 32 Bit
Drivers for Atheros AR5007 and Windows Vista
Although this driver has shown up in BSODs (Blue Screen Of Death) on Vista SP2 systems, usually conflicting with updated Vista OS drivers like netio.sys, tcpip.sys and other networking related drivers.

AR5007EG
Vista 32 Bit
Drivers for Atheros AR5007EG and Windows Vista

Drivers for other windows operating system
http://www.atheros.cz/atheros-wireless-drivers.php

Assuming that after all the above the wireless still does not connect to the internet, all I can suggest is to use wireless security of WEP or to get an external USB wireless card.

You might also bug your laptop's tech support about the problem--maybe people can put pressure on Atheros to find a fix.

I would advise you to do a dns flush and a dns register... I think that may resolve your issue, because it just seems as if the dns aren't resolving. If that doesn't work, go and manually assign your dns 8.8.8.8/8.8.4.4 and you should be good.
