yea, ive tried that, and it worked for about 2 days, then i started to get errors again.

It may just be one of them things you need to keep doing buddy

Do you want me to put a .bat together for you, just click and it will be done?

As this is not a major problem :)

im wondering if it could be something with my router? What if i assign my PC with a static IP?

Its worth a try mate, as i said its not a major problem its just annoying you.

Are you dropping internet at any point?

Dips in speed?

dips in speed mostly. but being that im only getting 2.8mbps download, its hardly noticeable. i just checked my mom's computer, and she has the same errors aswell.

Okay so i have done some research for you, do this for all the computers on the network.

Method two : Disable TCP/IP v6
To disable TCP/IP v6
1. Click Start, click Control Panel, click Network and Internet, and then click
View network status and tasks.

2. In the left pane, click Manage Network Connections.

3. Right-click Local Area Connection, and then click Properties.

4. In the pop-up box, clear the Internet Protocol Version 6 (TCP/IPv6) check box.

5. Click OK, and then restart your computer.

To enable TCP/IP v6

1. Follow steps 1 through 3 in the previous procedure.

2. In the pop-up box, select the Internet Protocol Version 6 (TCP/IPv6) check box.

3. Click OK, and then restart your computer.

Already disabled on my PC. Not my mom's however.

Try it on your mums, if that doesn't work try to assign a static IP Address.
