Router stopped working for MacBook only?

Bit of a weird one this, my internet suddenly stopped working a few days back. I thought it was just Virgin Media experiencing some downtime, thought nothing of it and went to work. Came back and still no internet access so I got on the phone to support after the usual process of restarting modem/router/PC etc.

Anyway, the guy made me do all the tests and everything came back fine. I had my Dad's laptop handy so I tried getting online via that (uses the same router) and it was fine, no problems at all.

Basically, my MacBook dosen't want to load any webpages etc if it's connected to the router yet it works fine if it's connected to the modem by a cable. Bit of a strange one as it's all been working perfect for the last 2-3 years, i've not changed any settings recently on either the router or the MacBook.

What would be causing this? I don't even know where to begin? :confused:
 
First things first, turn off airport and turn it back on, then if it's still not working, open up terminal and type:

ifconfig, then hit enter.

Then come back here and tell us what it says next to en1:, it should read something like this:

en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::21b:63ff:fe09:1bd8%en1 prefixlen 64 scopeid 0x6
inet 10.1.1.106 netmask 0xffffff00 broadcast 10.1.1.255
ether 00:1b:63:09:aa:aa
media: autoselect status: active
supported media: autoselect
 
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::21e:52ff:fe7f:5023%en1 prefixlen 64 scopeid 0x4
inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255
ether 00:1e:52:7f:50:23
media: autoselect status: active
supported media: autoselect
 
Right, so it is at least receiving an IP address from the router (which I assume is 192.168.0.1?).

From the terminal window, do you get a response if you run:

ping 192.168.0.1

If you do get a reply back from 192.168.0.1, what about if you try:

ping 8.8.8.8

Any response?
 
Sorry, I didn't make it clear - i've been accessing the net with my MacBook plugged straight into the modem - I don't have 2 network cables so can't test whether it works with a wired connection to the router...
 
Now I'm confused. En1 is the wireless (airport) adapter in the macbook, en0 is the wired ethernet.

Do you use wireless to connect your macbook to the internet? (or did you before it stopped working).
 
So, back to what I asked you to do regarding ping please :)

That has nothing to do with it being wired or wireless.
 
Yep I get a response on both...

Are you broadcasting the SSID? I had problems connecting with my Macbook - it would only connect when it was being broadcast.

He is connected though, so completely irrelevant.

The ping to www.google.com proves that he is getting external traffic routing correctly, AND that DNS is ok.

Next thing, do you have another browser to try besides safari? Do you have any proxy settings listed in network under system preferences?
 
I've tried Google Chrome and Firefox as well as Safari and no joy. Sometimes pages will load (after a good 5 mins or so) or i'll get the Virgin Media 404 type page saying this page cannot be found.

In the proxies panel I don't have any of the checkboxes ticked, I have the following in the "Bypass proxy settings for these hosts and domains"

*.local, 169.254/16

And Use passive FTP mode is checked.

I'll run the same tests when I get home just with the wireless connection...
 
^could be why he could still ping, probably taking the route through the wired connection, whether your wireless was working or not. If you have an ip, then id guess that your default gateway has got stuck on an incorrect ip, or the http traffic is still trying to route through your wired connection for some reason. I dont know who to do any of this on a mac though.

If the other guy doesnt manage to fix it for you ill give the Mac support guy here at work a shout.
 
Cheers mate it'd be appreciated, starting to become a pain now.

I ran the modem to the router, and just connected to that over wireless and it still managed to ping google.com and the 8.8.8.8 address fine...

I've also been able to load up google and the search results page but any other website just doesn't load/times out.
 
thats weird that you can ping but not get http traffic. Try resettingthe browsers settings (eg proxy/security etc) Is there a hijack this for macs?
