Network Issues

Charles Hawkins
All,

I’m pretty sure this is something in my personal network, so I’m looking for suggestions that are general.

I bought a “refurbished” iMac from OWComputing a few weeks ago.  Ever since I’ve occasionally run into a situation where internetwork access dragged to a crawl.  I have been experiencing it this evening, hence this post.

What I see is *extremely* slow loading of sites in Firefox, slow loading in Mail, not loading graphics or being very slow in Mail.

I’ve checked resetting my router etc, to no avail.  I.e., I still get situations where downloads/net access work as expected, but also cases internet access is slower than molasses running uphill in January.

I’ve checked everything I can think of.  Amy suggestions?

Chuck

Netflix recently launched a handy dandy speed test service that can be used whether you're a subscriber or not:


Sometimes rebooting both your modem and router will help. If this doesn't work, try connecting the iMac directly to the modem; if internet access is better, the router is the problem.

We live in a large apartment building and a few years ago we had a slowdown due to neighbors running wifi on the same channel.

Hold the <Options/Alt>-key down and select "Open Wireless Diagnostics..." from the Airport fan (WiFi) icon in the menu bar.

Thanks for your suggestions, and yours too, Marilyn.

I now think that the WiFi has failed in the new iMac.  I’ve experienced issues off and on today.  This evening I was trying to go t various web sites, and got that sluggish behavior again.  I restarted the WiFi router, and that made no difference.  In fact I kept getting notices that the computer could not connect to my WiFi.

I did some checking and my other WiFi devices were connecting with no problem (MBP, iPad, iPod Touch).  In fact access and downloading was snappy on the MBP, just like normal.

So just now I hooked up a hard wire connection for the iMac and that works fine, even though it still won’t connect via WiFi.

Hah!  I just tried the WiFi again and it connected.  

Weird!

I still think there is something wrong with the WiFi controller on the iMac though.
