My iMac's Internet Sharing has slowed over time

Hi Everyone,

I have a fairly (hopefully) basic issue with my iMac's Internet Sharing. I've been sharing Internet through my iMac over WiFi for a couple of years, and recently, the internet it shares has begun to slow. The iMac itself has very speedy internet, and the WiFi has been fast in the past, but over the last month or so it has slowed down. I primarily use this internet with an iPhone and sometimes some Macbooks (no Windows devices), and the previously fast internet speed has dropped to so slow that anything trying to load will end up timing out. What are some suggestions?

Thanks in advance.

iMac, Mac OS X (10.6.8)

First check w/your ISP to confirm that the slowness is not from their end.

Connect your comp to the ethernet. Still slow?

==============

Try the basics first:

Change your router channel number. Most times this works & is all you have to do.

Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.

System Preferences>Network

Click the Assist Me button.

In the next window that pops up, click the Diagnostic button & do the necessary.

Also, run the Airport Utility app which is located inside the Utilities folder.

If using a Linksys router, contact LinkSys Customer Support and/or post in their forums.

If using Apple's Airport, please re-post over in one of the AirPort Forums.

Nope. The issue definitely isn't the router/Internet provider itself, but more with the iMac's Internet sharing. Everything else works except for devices connected to the shared wireless internet. I did try to change the channel the iMac broadcasted to, but I'm not exactly sure if I did that correctly. Thanks.
