Windows 7 - Can only connect to google and a few other sites (different problem)

Hey there

I'm having a problem with my internet where I almost can't load any websites, only a few are working (gmail, google, youtube (cant load movies), sevenforums, and a few more)

It started yesterday evening while I was gaming, and hasn't been working since. I changed no settings on neither computer nor router.

The same problem persists on every computer we have - (tried an iMac, 2 desktops with Windows 7 and Windows XP, and an iPhone and an iPad) also tried both Wireless and with Cable. Tried resetting router settings and restarting everything.

My router is a ZyXEL P-320W


I have no idea what to do, anyone got any suggestions?

Thanks in advance

Sounds like dns.

Try this start>cmd>ipconfig /flushdns then ipconfig /renew. Does this cure it?

Hello,

Is it hard reset or soft reset? You might want to consider a hard reset to the factory default settings if all computers are affected. Re-configuring all fresh is a good practice, make a note of the current router settings. Prior to the reset, see if there's a new firmware version for your Zyxel router.
Please let us know.

Hey there. Thanks for answering both of you!

Zigzag:
I doubt it's DNS when all computers in the network got affected at the same time, tried nonetheless without positive result

2xg:
I think it's a soft reset, just did it in the router settings in 192.168.1.1, how would I perform a hard reset?

And no there isn't a new firmware version

Here's your answer.
Pls. don't forget to do print screens on make a note of the current settings before resetting to the factory default.

I can't open almost all sites on the internet, and sevenforums is an exception. (Don't have a job atm, so can't really go there..)

Can you or someone else please post how to make a hard reset here on sevenforums? I would be most grateful

Opened the website cached from google, so tried it and it didn't work. Still nothing..

Could the problem be at my ISP? Or maybe I need a new router? It's around 4 years old afterall

Okay. I just tried with another router, and the problem persists - so the problem has to be caused by something else

By now I'm pretty sure it's my ISP

From this site: ZyXEL Support & Downloads - FAQ

So the problem disappeared overnight just as random as it came.

Thanks for helping everyone
