So, here's something weird...
I have 3+ networked devices connected to my network, 3 of which are Windows 7 PCs, one out of the three can't resolve anything. When I ping Google DNS I get responses on the other two machines but not the trouble machine
The trouble machine is getting addressed no problem and can ping the router but DNS will not resolve.
The other thing I noticed is that when I go to ping the trouble machine I'm not getting an IPV4 address, it looks like an IPV6 address (the thing is I disabled IPV6 on all my Win7 machines)
I thought it might be the router but I've soft rebooted it a couple of times, so I'm confuse?
Incidentally I've run ipconfig /all and compared settings and as far as I can tell the adapter is set up the same across all three? But I figure if it was a problem with the router I would see it on everything and not just one machine?
Can you give us an IPCONFIG /ALL on the problem machine, and one of a working machine? Take a picture with your camera on your phone if you can't get the text off the machine. Next open up your C:\Windows\System32\Drivers\etc folder and past the contents of your hosts file.
Next is run a MalwareBytes in safe mode on your problem machine if the above checks out.
I'll check the hosts file, never even thought of that
After work when I have time to mess around a bit more I'll post my config stuff side by side
Very annoy
EDIT: ...I think I'm going to hard boot my router, some weird stuff going on
It looks like PEBKAC
I disabled the DNS relay option on my router, the thing I don't get is how 2 machines out of 3 were still able to resolve DNS without problems
Verr Strangggge
This problem is persistent
How could it be that LAN DNS resolves fine for everything but WAN DNS resolves for everything but one device?
All I can think of at this point is some malware or something hijacking DNS on that machine???
If you can go through the steps above so I can give you a better idea of what could be the cause...
Do you have DNS specified on the two machines that work, and not on the one that doesn't? Maybe go into the properties of the connection on each machine and go into the advanced properties for IP4 and compare between the machines.
Also, if you think it's malware of some sort then doing a MalwareBytes scan in safe mode is a good idea. That'll at least rule it out, if nothing is found (yes, I'm placing a lot of trust in MBAM).
SO, I disabled the router's QOS settings and all of a sudden I could ping all machines across my LAN without any problems, then I lost WAN DNS (!?!)
So ... I reset my router to factory default and now things APPEAR to be working.
I have no idea why the QOS engine would pick on just the one machine, or what the hell was happening but it's all good now...
Time for a new router I think
[suspicious]DLink DIR-655 for those interested[/suspicious]
Highly recommend Asus RT-Nxxx or RT-ACxxx models (AC if you have lots of money). I've bought myself one, I think Lazy has one and I know 4 others in the office that moved from DD-WRT/Tomato compatible routers to them and haven't even changed the default Asus OS. Night and Day in terms of performance as well!
Nice, that's what I should have...
Do you have to SSH in to administrate it or does it have a web access portal?
Web access all good and sexy... but does allow SSH if you want.
Awesome, when I get back I know what I'm buying :)

Well but which ones? MemEx has the RT-N10 for $39.99 all the way to the RT-AC87U for $359.99. And they all seem to claim the same thing (300,000 data sessions, AiRadar for better signals, multiple networks for separation, etc).
From what I understand the difference between routers is usually available memory
A home router that's expected to deal with less traffic ships with less storage whereas a small business router will have more
For N I would recommend: http://www.memoryexpress.com/Products/MX37448
For AC I would recommend: http://www.memoryexpress.com/Products/MX48122
But depends on your cash flow and needs. I love my RT-N66U and would say the Ram and CPU on it are sufficient for my heavy 2 person internet needs. I don't expect to have any AC devices for another 2-3 years.
Mr. A, sorry about sending this thread into router discussion land.
Mel, those are the ones I expected you to recommend :)
Looked up on wikipedia to see what devices might be using 802.11ac: http://en.wikipedia.org/wiki/IEEE_802.11ac#Commercial_handsets. We have a Samsung Galaxy S5 and S6 in the house, those use it. Our iPhones are older, they're 4Ses. Our iPads and other tablets and laptops are older, too. Still, I wouldn't mind that AC unit.
Now I just have to bite the bullet and get the Shaw router switched to pass-through mode (bridged? whatever they call it), and then find another power plugin (they're all full at the moment).
And then I could buy a new computer so my eight-year-old Dells can be retired.

Melbosa's recommendations are solid, if you keep the base ASUS up to date it is very good. If you need a few more features the merlin firmware http://www.lostrealm.ca/tower/node/79 is also good.
