I'll ask the obvious question first, has he installed the drivers?

Monster ninja · 23 Dec 2011 at 19:01

yes I have installed the drivers

Tried reseating the card? Although does it get detected first.

Assuming you're using windows? have you ran through the networking troubleshoot wizard?

So, when you say it can connect to the internal network, is it able to ping the default gateway? What happens when you do an 'ipconfig /all'? Perhaps it's not being assigned an IP Address for one reason or another. When you go in to device manager, is there any indication that the device may not be functioning as it should (yellow exclamation mark e.g.)?

try reseating, using windows 7, tired the networking troubleshooting wizard. the odd thing is it somtimes starts to connect then just dies

Also, how are you connecting? Through WPS or typing the router's code in? Also, as the others have suggested, try and reseat it, be sure to check for dust as well.

Monster ninja · 23 Dec 2011 at 19:11

its all a brand new rig so there should be no dust, just connecting as normal to the router

Im going around his house later and i am going to take my Edimax EW-7728IN PCI and see if that works? guessing if that does the network card is dead, had it for less than 28days so its a replacement?

SO you can see the wifi network in Windows?

If so then try...

Have you tried to manually configure the wireless connection?

1. Open the Network and Sharing Center
2. In the left pane click Manage Wireless Networks
3. In the list of networks right click your wireless network and click Properties
4. Click the Security tab and check its settings

Check that the settings are the same as your router, i have seen problems where WPA was chosen instead of WPA2 or that TKIP was chosen instead of AES encryption.

Ensure the settings here resemble the security settings on your access point.

ok i will try all this later on

Monster ninja · 24 Dec 2011 at 00:15

update

I have used my network card in his rig and no luck, same problems

here are the screen shots i have taken, it says :wireless connection does not have a vaild IP config" ?

the last 2 screenshots are taken when my network card is installed

EDIT:
give me a min to change the size, Photobucket has changed it...

Monster ninja · 24 Dec 2011 at 00:26

edit i cant upload at full size? but it says that "wireless connection does not have a vaild IP config"

J.B · 24 Dec 2011 at 00:29

Can you ping 8.8.8.8?

Possibly a DHCP issue where it's not being issued an IP.

Very common, don't worry. Card is fine.

Make and model of router? ISP? Any other laptops/PC's connected to network and via what? E.g. Ethernet or Wifi?

Does this PC in question work OK if connected to the router via an ethernet cable? If not... it's an internet issue and not a software/hardware/network card issue.

If it does connect. Log onto the router using it's I.P address. Simply type it into the address bar in your browser. To find the I.P.

Open CMD, type "ipconfig" Default gatwat: 192.168.x.x.x.x That is your routers I.P.

Log in. Password and Username are usually on bottom of router. If not. Defaults are usually, "admin" "admin" / "admin" "password" / Orr "admin" "leave blank" (Don't actually type "leave blank obviously*.)

Once in. Find wireless settings. Change encryption to WPA2-PSK if possible, If not. WPA-PSK. Change passkey to something memorable. Any password really. Also change the SSID to something else, (street name or whatever)

Now in start menu, type "configure wireless networks" Open it. Once in... delete all previous wifi networks.

Now rescan for networks using the tool in system tray. Find your new SSID. Connect using your new passkey you just made.

Now try pinging google. In command prompt... type. "Ping www.google.com"

If you don't get a reply and you get a timeout. Log back into router and confirm all ADSL settings are entered... username and password etc. If not. Contact ISP for details.

P.S. Don't forget to save settings in router config after changing them and switching pages.

--------

God I hate wifi troubleshooting. I always get it done in the end using these steps (I've done it tooooo many time) It can be so frustrating... especially running around the house resetting routers and ripping phone wires out.

Failing all this. Call someone local who knows what they're doing.

Hope all helps.

Ohhh.... Settings wont be wrong or mis matched with regards to AES or TKIP as if you scan and connect via the dialogue box. Windows configures this for you and recognised the encryption used on the network. It doesn't get mixed up and use the wrong one. Only if entered manually. Which is a waste of time really as the scan feature works fine!

Also make sure "UPNP" is enabled in the routers settings. If ticked this will eliminate any DHCP issues. Most routers are configured to spit it I.P. automatically and very rarely this is turned off. If it's connected to the network, just not the internet. It's already received a local I.P. and again... not the issue.

I do this as a job btw *Sighs* Should have stuck to judo coaching! A lot less stressful.

It's worth going into the network connections. Right click and select properties on the icon for the wireless adapter. Highlight IP V4 (TCP/IP4) and click properties then advanced on the box that pops up. You want to manually add the default gateway so you need to know the I.P address of your router. It's usually 192.168.1.1 but can vary depending on the brand of router.

Hope that helps

I'd advise against fiddling with the router too much. If other computers connect to it fine and have internet access dont fiddle with the SSID and passphrase. It's clearly not the router, it's the network settings or the card itself. Try adding the default gateway before doing anything else then post back, we can go from there

Hmm that does sound very confusing. Could still be a number of reasons though...

1) Are there any thick wall/floor partitions between the card and router
2) Any electrical equipment between them (e.g. microwave), also try changing your wifi channel.
