Possible iMac/Wi-Fi problem?

[acrahm]

Hope to find a little help here with an issue i have been having with my imac for the past week. Simply stated, my imac is having problems connecting to my network.
The odd/unusual thing though is email still works, but any browser doesnt connect to any websites (safari, mozzila etc).
Whats even more strange is my iphone, ipad and relatives laptop connect and have no issues.
I re-start my imac and everything is back to normal and i can connect without any problems

Anyone seen/heard of this issue before and have any ideas of what i can do to fix it so i dont have to re-start my computer a couple times a day?

thanks!

what message do you get when you try and visit a website? Can you get to your router/hub's admin page from a browser?

It says cant connect to to server. I can get to router/hub domain from a browser

Long shot, but it might be worth adding an address of 8.8.8.8 to your list of Domain name servers. It's an advanced option from network settings.
