Signal strength: Very good, Access: Limited connectivity

Hi, I've been away camping for a couple of weeks and now that I'm back my desktop computer no longer connects to the internet. As I state in the title, however; the signal strength says it's "very good".

I've tried removing the connection and re-adding it, I've tried moving the wireless USB/removing and potential disturbances, but to no avail.

Any help would be much appreciated!
 
Turn off the Modem
Turn off the Router
Turn off the PC
Turn off all network gear

Do this for 30 seconds.

Then slowly turn on the modem (DSL or Cable)
Then the router
Any switches
Then the PC
Then the rest of your network.
 
For a second, I thought it had worked, but it was just taking slightly longer than usual to tell me that the page hadn't loaded...

Any other suggestions? :/

Thanks tipstir, here's what I got:

Okay what are your results now when you ran the TCP flushing, does it connect to the internet? Also in your Router does the Router see your desktop? Can other PCs on your network get out to the internet?

Check the adapter settings and IPV6 is disabled.

Try also this
Select flag (orb)
select all programs
select accessories
select dos prompt (but right click on it)
select run as admin

[FONT=Tahoma]type: sc start Dnscache[/FONT]
[FONT=Tahoma]type: sc stop Dhcp[/FONT]
[FONT=Tahoma]type: sc start Dhcp[/FONT]
 
I followed those instructions and got this:

I'm hoping the "NOT_STOPPABLE" stuff isn't bad news?

Sadly, still no internet. I'm not sure how to check if the Router sees my desktop, but I'm almost certain it's connected. Here's what the computer's saying about the connection in the Network and Sharing center:

Our other desktop and the laptop I'm using now don't seem to have any trouble accessing the net, so I really don't see what the problem could be :/

Use this example as yours is on Public Network this one above is on Private Network.
Also was there someone using this PC when you were away? Did you have a brown out?
Was the PC on while you were away.

Press flag + r
type cmd
type ipconfig

IPv4 Address
SubnetMask
Default Gateway

Post the ip address your getting?

That USB adapter for WiFi which make is it? Does it have any status light on it.
Try updating drivers for it. Or try to switch it out for another one. Or just replace it.
 
Only family members used it, I believe. And even then, not on administrator accounts.

The IPv4 is 169:254.115.30, the Subnet Mask is 255.255.0.0 and the Default Gateway is blank.

The adapter is a Netgear WN111v2, as far as I can tell. The status light is on solidly. I'm starting to think I may just have to buy a new adapter... It is a few years old now.
 
169:254.115.30, look at your other PCs do they have the first 3 sets of group numbers: 169:254:115:xx

If not then your using a what we call a private IP. This is not what you want to use.
Let's say the other PC is 192.168.1.10 Then this PC needs to be set to 192.168.1.20.

IP address: 192.168.1.20
Subnet Mask: 255.255.255.0.0 (really should be 255.255.255.0) check the other pc
Default Gateway: 192.168.1.1 (this is your router IP address) check the other pc

to get the info from the other PC
Press flag + r
type cmd
type ipconfig

On this PC giving you issue, you need to enter in a new IP address this is what we call static IP.
But before you can even do that you need to see what the other PC ipconfig is?
 
The you need to go to the adapter settings and change it to 192.168.1.9 for the PC that is acting up on you.

Open the control panel
type: connect (in the right top side box)
click on view network connections
right click on wireless adapter
click on properties
select Internet Protocol Version 4 (TCP/IPv4)
click on properties
change from obtain IP address automatically
select Use the following IP address:
type: 192.168.1.9
type: this will drop down auto when you tab to it Subnet Mask (if not do it manual)
type in default gateway this is your router.
change from obtain DNS server address automatically
select use the following DNS server address:
type: your router IP address here.
click ok
click ok
wait for the system to update the new settings
reboot the PC.
 
I am now typing this message from the formerly problematic computer. :)

It works!

Thank you very much, tipstir. I'm certain I would never have been able to get this sorted without your help. You're awesome.
