Hello Everyone. I am new to this forum. I have a PCI wireless card on my desktop(TP-LINK TL-WN353G) and I keep trying to connect to a network but I fail. I have Windows 7 Ultimate 64 bit. My laptop can connect but desktop cannot. Whenever I connect to a network it says "Unidentified Network" and "No Internet access." When I went into the troubleshooter, it said "Problem with network adapter or access point." I opened up my computer and checked to see if it was properly in place. It was but it still cannot connect. The adapter detects the network and connects to it but internet does work(I am currently using my laptop) My PC specs are:
Intel Core i5 650
Intel DH55HC
4 GB RAM
Seagate Barracuda 1 TB Hard Drive 7200RPM
HP DVD Burner
450 Watt PSU
Windows 7 Ultimate 64 bit
I googled the problem, reinstalled the latest drivers, tried anything i could think of but without success. I want this problem fixed ASAP and please reply as soon as possible.
PS: I cannot try it with Ethernet because the modem and router are in the living room and my desktop is in my bedroom which is far away from the living room.
btw i have a scientific atlanta Wireless G router and my ISP provided the modem.
It cannot be a router or modem issue because the internet works fine on my laptop. The issue is only with desktop. I also tried repositioning the tower but that did not work either. Please help and I checked to see if it supports Windows 7 Ultimate 64 bit and it does. What's the issue? :4-dontkno

Re: Wireless connection problem on desktop?

can we see a few things
ipconfig /all - device manager - xirrus - and services
quite a few things - but as you do not have internet access - i thought the full list so you can copy everything over in one go rather than bit by bit


------------------------------------------------------------------------
{ipconfig /all}
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

We would like to see the results from ipconfig /all post back the results in a reply here

Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results to notepad and then automatically open notepad.

Now all you need to do is copy and paste those results to a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will be highlighted
Next
From the notepad menu - choose Edit - Copy
Now go back to the forum - reply and then right click in the reply box and paste

Direct link to the program is here Xirrus: The Leader in High Performance Wi-Fi - Advanced IT Wi-Fi Networking Tools
Then run and install the program
if you get an error - You need NET Framework installed for the WiFi Inspector to function.

Run the program

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.

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

------------------------------------------------------------------------
{Device Manager}
Post back the results in device manager
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
Start > control Panel {Vista set to classic view}> system > {Vista, device manager on left hand side} {XP hardware Tab, device manager button} >
windows 7
start > control panel> System and Security> Device Manager

network adaptors, click on the + > post back the devices listed there
are there any ! ? or X


post a screen shot of the device manager - network adapters

{Services}
post back the status - started/stopped and automatic/manual
Check your Services are Started on all PCs:

• COM+ Event System (for WZC issues)
• Computer Browser
• DHCP Client
• DNS Client
• Network Connections
• Network Location Awareness
• Remote Procedure Call (RPC)
• Server
• TCP/IP Netbios helper
• Wireless Zero Configuration (XP wireless configurations only)
• WLAN AutoConfig (Vista wireless configurations only)
• Workstation

Note: You can check the services in Control Panel, Administrative Tools, Services.

All of these services should be started, and their startup type should be automatic (or perhaps manual).

If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running.

Checking the event log is also a good idea here, there may be clues to what is failing.
Start > control panel > administrative tools > event Viewer

Re: Wireless connection problem on desktop?

Ok -
so the adapter can see the wireless - although quite low in strength
all the services are running
and windows was unable to assign an IP and so assigned 169.254.x.x

so a couple of things to try
1) What firewall do you have on the PC , Norton or Mcafee etc etc
Have you ever had in the past one of these firewalls - they can still block despite being removed in the past !!!! - and need to be removed with the removal tools
2) TCP/Ip reset

------------------------------------------------------------------------

TCP/IP stack repair options for use with Vista/Windows 7.

Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Note: Type only the text in bold for the following commands.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

If you receive the message
The requested operation requires elevation.
Then please open the command prompt as administrator - as requested above
Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.


Post back the results here - we need to know these commands worked correctly
rightclick in the box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Re: Wireless connection problem on desktop?

for the reset winstock entries command, it says, " The following command was not found: winstock reset catalog

for the reset ipv4 command it says," resetting interface,OK!
Restart the computer to fix this action"

for the ipv6 command it says," there's no user specified setting to be reset"

 

[etaf]

Re: Wireless connection problem on desktop?

winstock reset catalog

is that a typo here or when you entered the command
NOT winstock

 

[taimurtk100]

Re: Wireless connection problem on desktop?

oops sorry i re-entered the command and it said something like "action completed restart computer". i rebooted the computer but the problem is not fixed

 

[etaf]

Re: Wireless connection problem on desktop?

so we are left with firewalls - what have you on or ever had on the PC

and a restore

start>programs>accessories>system tools>system restore > choose a date before the problem started

 

[taimurtk100]

Re: Wireless connection problem on desktop?

about the firewalls... i have the standard windows firewall. Doing a restore would be no point because the computer is brand new and the problem was there ever since I bought it.( I bought the PCI card and put it in the PCI card slot later)

 

[etaf]

Re: Wireless connection problem on desktop?

the computer is brand new and the problem was there ever since I bought it.

has this ever worked ?

log into the router and remove the WEP security and see if you can connect with NO wireless security

the signal is border line for a good connection - can you change the position of the router or adapter aerial and see if you can get a stronger signal on xirrus

 

[taimurtk100]

Re: Wireless connection problem on desktop?

i tried the above but it still does not work

 

[etaf]

Re: Wireless connection problem on desktop?

can we see an xirrus screen shot - with no security

has this ever worked ?

and did you try to improve the signal ?

what happens if you click on the connect button on xirrus

 

[taimurtk100]

Re: Wireless connection problem on desktop?

never mind... the problem is now fixed. I called a computer expert to my home and he downgraded my OS to windows 7 Pro 32 bit and it worked. Apparently the 64-bit OS was heavy and browsing was really slow on it so he installed a 32 bit OS

 

[Wand3r3r]

more likely the x64 wireless driver was incompatable but thanks for updating us on your solution.
