I keep getting 'you have 2 computers with the same id at that internet address' messages when online.

When filling fields online, frequently only the 1st few letters or none make it into the field, or when typing in the address line of the browser to go directly to a website (www.hotmail.com etc), frequently only a few or no letters make it in to the address line.

I think I might need to scrub & reload my windows (7, I think). I have the disc that came with the pc but it doesn't seem to be as straightforward as that.

Hmmm, the router is connected to the phone socket but there is also a thicker yellow cable from the router to the computer. So yes, I think that could be the case. Should the router just be connected to the phone socket and nothing else?
 
When I disconnect the router cable from the back of the pc, it can't get online (I do have wifi set up for tablet etc).

The problems that I have are only on the pc.

OK. Open a Command Prompt with Administrator rights and type in IPCONFIG /ALL and hit <enter> You should get a long list of items. Please repeat the command IPCONFIG /ALL > C:\IPCON.TXT and hit enter. This will send the output to the file C:\IPCON.TXT (in the root directory of Drive C) Please post this file for us to review.

I see the word 'Teredo' in the generated text file, having worked on timber rail bridges I don't find the inclusion of this word in any way reassuring.

Hmmm.... Nothing untoward there. There appears to be no wireless network card in the machine. Try disabling IPv6. Open Network & Sharing Centre. Click on Change Adapter Settings (at the top left). Right-click on the Realtek Adapter, and go to Properties. Remove the tick from "Internet Protocol Version 6" and click OK. Close all windows on the way out, and then restart the PC.

Did that & put a new keyboard on it, the typing thing seems to be fixed but this morning I got the old 2 computers with same id message. It said that more info could be found at the Windows System Event Log.

There are several ways to solve these things, I think the router is trying to give an IP address that is already taken. So, a Laptop is given the IP address 192.168.0.2 everything is turned off and the desktop PC is network connected before the Laptop and is given the IP 192.168.0.2 the router then tries to assign that IP to the laptop and you get the ID message/error.

Fix 1. If the desktop computer is static (Never moved) and is always connected to the network, why not manually give it an IP address, such as 192.168.0.20 and the subnet mask would be 255.255.255.0 The DNS sever would be 192.168.0.1 which is the routers address. I chose the IP address 192.168.0.20 to remove the chance of IP clashes.

Fix 2. Turn off all devices including the router. Unplug the router power from the back of the router and press the on button - if it has one for 10-20 seconds, this dissipates power from the capacitors and truly turns the router off. Now reconnect the routers power cable and turn it on, let it settle and all lights are on. Now turn one device on at time wait for it to boot and is given and IP address, this can be confirmed using a Command Prompt and IPCONFIG /all
Once an IP address is confirmed boot the next device and do the same thing. This should help the router automatically assign IP addresses to each device via DCHP (Dynamic Host Configuration Protocol) this method generally sorts out IP Conflicts.
