i have my puter setup through a router, which is all fine and dandy, but i cant check my yahoo mail, and i cant upload photos, and then sometimes certain webpages wont do anything at all, i have to plug straight into my modem to do any of that, which is really aggravating when you're trying to do stuff in a hurry, oh well, some help would be nice please
Type in your default gateway (mines 192.168.1.2) then change the settings. Pple will need to know what make model ect your router is to help more.
model number would be better, this site probably has what ur lookiing for but might be confusing to understand, was for me :S www.portforward.com
if you don't have special settings that was set by your ISP, then I'd press the restart button to restart it to factory default, then you can build it back up to where you were, and see if you messed anything up... (I had to do that on my netgear once, It wouldnt let me undo the crap that i did to it, so I restarted it....)
