Solved Windows 7 - Connected but no internet access - help needed.

[Beagle]

Hi,
I've recently changed ISP and now have a new router. Everything else connects to the network perfectly (a Macbook, PS4, TV, 2 phones) apart from my Windows 7 PC. I've disabled IPv6, tried flush dns, reset winsock etc. I'm not even able to log into the routers setup on this PC.
Sometimes, I have the yellow warning triangle over the wireless connection icon with the message "no internet access". Other times I will not have the yellow triangle, it will say I have internet access, but I'm unable to load any webpage (including router). Any help very much appreciated!

1. Is this a wired or wireless connection issue?
Wireless


2. Who is your Internet Service Provider (ISP)?
Zen

3. What type of Broadband connection are you using?
Cable/Fibre optic

4. What is the exact Make and Model of your Modem, Router or Modem/Router Combo
Modem is BT OpenReach. Router is Asus NT-56U

5. What is the Name of the Anti-Virus, Security or Firewall Software installed from the problematic computer - McAfee, Norton, Eset, Webroot, Zone Alarm, etc.

Is that ipconfig output form faulty win7 machine? So it has ip address 192.168.1.30?
You can't browse to 192.168.1.1?
Can you do in command prompt:

ping  192.168.1.1

post output
Can other machines ping the router?

Hi,

Yes that is from the faulty machine. I can access the router perfectly fine on my Macbook.

Here's the ping response:

What happens if you boot into safe mode with networking? Can you then ping the router?

Hi BJB, I shall try that tonight.

Here you go:

I can see you can tracert 198.211.122.92. So you're connected to internet.

Hi Kaktussoft. Here're those screen grabs.

tracert 198.211.122.92 still gives same output? see post #8

Just tried safe mode. It says I have internet access, I can ping the router. All seems to work - I can even log into the router!

What happens after a clean boot? http://www.sevenforums.com/tutorial...ation-conflicts-performing-clean-startup.html

Yeah, similar results for the tracert (some time-outs) and pinging 198.211.122.92 gave 'request timed out'.

Odd... I was able to load a couple of webpages about 10 minutes ago and ran a speedtest.com test, which gave me good results (ping 12, expected download and upload). But now it can't even complete the test - it's stuck on Ping 29ms...

I'm going to try a clean boot next.

Just did a clean boot and the problem remains. Connected to internet, no pages load, unable to ping 192.168.1.1

In safe mode with networking you can ping router and logon to router? You can browse the web? It is not pure luck.... it works all the time?

revert the boot to "normal boot".

argh...must have been luck! Just rebooted into safe mode and I can't ping router or log on. Well...the browser asks me for the admin password but after that Chrome just hangs and nothing happens.

I would connect it by cable and try to update the wireless adapter driver.
