Wireless Connection Problems

[Isildrae]

Hey there,

I've recently got a new PC and installed a Wireless card that was previously running on my very old PC with no problems. Ok so my network has other stations (wired and wireless) running perfectly fine, connecting both to the router and the internet. My new machine however can see and connect to the router, but it says that I have no internet access.

The devices on the network that work with no problems are as follows:
PC (7 years old) - Wired Connection - Windows XP
MacBook - Wireless Connection
XBox 360 - Wireless Connection

Now I have tried a Wired connection with my new PC and it works fine, unfortunately this is not practical and I hope to get the wireless working.

Below is the IPConfig from my new PC. It is Windows 7 and has the latest Service Pack. My router also has the latest firmware and the latest drivers are on the Wireless Card. I have also tried rolling back the Drivers, but to no avail. I have tried various combinations of resetting the router, the modem and PC and have reset the network and started a fresh, but still the same problem appears.

Previously in my struggles the problem seemed to be with the Default Gateway (After Diagnosing, the system replies that "The Default Gateway Is Not Available" has now been fixed.)

I am obviously frustrated and have poured over various help sites. I have been able to gain an internet connection, after Diagnosing, the machine seemed to connect fine, for about ten seconds, then it was almost like something had been reset or switched off. To my un-computer literate brain, it seems like the problem most probably lies with some settings on my new PC or a problem with the Wireless Card. The Router and connection work fine with other machines and even the problem machine when it is wired.


In the IPConfig I have included both the Wired and the Wireless connections. The net works on the Wired regardless of whether the Wireless is enabled or not. I figured it may provide some insight as to why the Wired works and the Wireless doesn't.


...here is my system information.

POWER SUPPLY - 500W RECON BRONZE PSU
MOTHERBOARD - P7P55D LE MOTHERBOARD
PROCESSOR - INTEL i5-750 QUAD CORE
CPU COOLER - AKASA X4 CPU COOLER
MEMORY - 4GB DDR3 - 1333Mhz MEMORY
HARD DRIVE - 500GB SATAII
OPTICAL DRIVER - DVD REWRITER
GRAPHICS CARD - XFX RADEON HD 5770 XXX 1GB GDDR5 PCI-E 2.0x16

WINDOWS 7 HP (64 bit)


Many advanced thanks for any help received.

Josh.

I see from your output that you are connected to your router bothe wired & wireless. Unplug the ethernet cable and report back.

 

[Darkmage]

I am also experiencing the same problem. I can connect to my wireless network without incident. Windows reports a solid connection consistently. But I get about 5 seconds of proper connection and then it just... stops. This will last for a few minutes and then I'll get another 5 seconds of good connection.

Swapping in another wireless card did not help. So it goes back to the store today and the original card is back in its slot. Problem has persisted throughout that process.

It's not just the internet. Connecting to the web-based router configuration screen is also affected. As is connecting to any shared network resources. When your router's web page times out, you know you have problems.

I do not experience this problem with other internet appliances in the house. The Unix laptop, the WinXP laptop and the various smartphones do not exhibit any connection problems. The wired Win7 machine works fine. It's only the Win7 64bit desktop that has the problem.

Welcome to the forum, Darkmage. What anti-virus and firewall are you running?

 

[chev65]

I'm not familior with that particular default gateway. Are you using another type of third party firewall? You didn't mention which brand make and model of router you are using? You may need to disable DHCP on some other device in order to pick up the correct default gateway.

I mentioned somewhere in my giant first post that I only did ipconfig with both connections on, because it may give some insight into the connections working. There is no noticable difference when both connections are running compared to when one is.

Short answer: Tried it. No luck :-(

I'm not currently using a 3rd party Anti-Virus or firewall. I wanted to get the net working without before going through no doubt more problems. The default gateway was changed to 192.168.7.1 (from 192.168.1.1) due to a suggestion someone on anoher forum made. It seemed to have no effect however.

I shall hunt out the make and model of my router when I get back from work.

 

[Isildrae]

Router is: Netgear WGR614v6

let me know if you need anything else.

 

[metalmania31]

How come your router is outputting the dns address? I think that's your problem.

 

[chev65]

Router is: Netgear WGR614v6

I believe that using an incorrect default gateway is the source of your problems. It's obvious that he had you set it up manually which should not be needed. The type of router will determine the correct default gateway you should be using.

For netgear you should be using 192.168.1.1 as the default gateway. I would make sure that DHCP is enabled in your routers control panel and also your network connection properties and perform a reset procedure on your router and see if that changes anything.

 

[Isildrae]

Just a quick bump as I finished typing.

If my problem is that my router is putting out the DNS address, how could I fix that? Set it to get automatically?

Strange as every other device in my house works fine.

 

[chev65]

You will need to go into your network connection properties and make sure that DHCP is enabled.

Your DNS will correct itself once you perform the router reset procedure.

[Isildrae]

I will try switching back to 192.168.1.1 tonight, but it has also already been tried. I've performed several router reboots over the last couple of days and nothing seems to change. I'm starting to think it may well be an inherent comparability issue with the Wireless card. Is that possible or common?

 

[metalmania31]

Yeah, chev65 laid it. As to how your other computers are getting through I don't know. The router should be set to the default gateway and dhcp. Your computers should be set to automatically obtain an IP address. The DNS server should be coming from your ISP and your computer should also be detecting that automatically.

Awesome, well I will try all suggestions in a coupla hours. Apologies for not being at the box now, in opera, I can't go home until the fat lady sings...

 

[chev65]

If this problem is only with one Windows 7 machine then yes it's possible the driver isn't working correctly, although the default gateway was not correct for a netgear router so this could be a router firmware problem.

You can also try to manually enter the correct default gateway 192.168.1.1 into the connection properties window of the problem machine as in the picture below but this step should not be needed.

If this problem is only occuring with a single Windows 7 machine then you might try updating the firmware for your Netgear router because you shouldn't need to enter the default gateway manually using DHCP unless your router isn't working correctly with Windows 7.

Well, the good news is that I solved my particular problem. It turned out to be wireless network interference, of all things. Interestingly, it is between my wireless network card and my wireless XBox-like controller for the PC. The wireless dongle thingy makes my connection unbearable.

When I unplug the dongle, all is right with the world. Updating the drivers on the dongle didn't help, so I'll just have to unplug it when I'm doing anything online.

Oh, and thanks for the warm welcome!

 

[Darkmage]

Looking at Isrildae's OP... I don't think having the default gateway at any other address than 192.168.1.1 is the problem. One of my older Linksys routers defaulted to 192.168.123.254 out of the box and I never had an issue with it.

If she's connecting with DHCP enabled, I think the best thing to do is just let the router assign the gateway. That way it will give him/her a centralized place to change it.

My first suggestion would be to try and learn from my issue and look for wireless interference problems. Try changing the channel of your wireless network at the router and see if there is a change in behavior.

My 2nd suggestion is to double-check the DNS servers that your router is picking up from your ISP. My ISP's DNS servers are awful and crash occasionally. A quick Google search on "open dns servers" will lead you a list of more reliable & faster DNS servers to improve lookup times. You can assign you router to use those DNS servers instead of the ones your ISP provides. It might help.

If that doesn't cut it, you may wish to try turning of the IPv6 capability on your network connection. (look at chev65's far-left image for where you can disable this for that connection). That might help, but it's a long shot.

I am glad you got your problem solved. Interesting solution.

If everything did not work to resolve the issue. A simple system restore to a later date before the problem on the driver occur, can solve the problem.
