Is this a common issue

Hi there guys.

I am having a bit of an issue with my O2 connection at home, to be more specific, the wireless from the O2 router.

I have 1 PC and 1 Laptop in the household and when the Laptop is on and connected to the net via wireless then all is well and works fine. However as soon as i turn on my wired main PC, the wireless drops out on the laptop and even though it can still see the connection it cannot connect

.

I have recently installed the O2 software on the laptop to see if that would solve the issue but it is still the same.

Is it an issue with the O2 setup or the wireless on the laptop?

Cheers for reading, any help is much appreciated.

Are both computers trying to use the same IP address?

Open a command prompt by typing cmd into a Run box [Windows Key + R]

In the command prompt type ipconfig /all A whole bunch of stuff will come onto the screen.

For your PC look for Ethernet adapter Local Area Connection or similar and find the IP next to IPv4 Address. You may have to scroll up through the output to find it.

Do the same on your laptop, only this time you will want Wireless adapter or similar.

If both IPs are the same then you have found your problem

Although normally Windows has a paddy if it detects the same IP on the network, worth checking still.

I work in IT so that was the first thing i tried

, but cheers, can often be the simple things that get overlooked

Main PC is using a fixed IP of 192.168.1.67 and the laptop, when it was connected before the Main PC was switched on is registered on the router as using 192.168.1.64 so there is no conflict there.

When i ping the laptop address, however, i get a 'Destination Host Unreachable' as opposed to a timeout message.

/edit

and just to add, before i installed the o2 software on the laptop, when the main pc was switched on the laptop would try and get an address via DHCP but was unable to get one was given an APIPA (169.254.xxx.xxx)

I have now also set the laptop to a fixed IP address to see if it was the DHCP that was having issues with mixing static and non-static IPs.

Still no joy yet though

Just a quick update on this. After setting both the Laptop and the Desktop to Static IPs as opposed to dynamic (drew a blank when i was trying to think of the name in my previous post) they both now work happily together.

I checked and double checked the IPs previously and they definitely weren't clashing so no idea what was going on.
