Mac Airport Issue

My Windows wireless connection is great.  However, my Mac is acting strangely.  The connection seems to go up and down in strength and it seems like the Airport is constantly scanning for networks.  Throughout this, my download speeds are fluctuating wildly.  I was making some firewall changes in relation to this machine and I'm worried that I messed something up.  I'm pretty knowledgeable when it comes to networking and this problem seemed to crop up after the Uverse installation.

 

Any thoughts or suggestions?

I had this problem in the past with comcast or so I thought and it turned out it was the Airport did the last firmware update and have not been

plagued with it ever since also running 10.5.5 may have had something to do with it.

Well, the installer set a specific wireless channel.  I just changed it to Automatic and it seemed to help.  It may be that I was getting interference from other sources and this might have caused part of the problem.  As of now, I'm downloading something and it's coming through at a great speed and seems to be holding steady.  I'll have to keep watching and researching.

If you think you are having wireless interference issues...do what I did.  Log into the MDC (192.168.1.254/mdc) and change to different channels 1 at a time, each time you change take the IP address of your computer (usually 192.168.1.xx) which you can find in the device list and use the systems tests to ping the computer.  Find the channel with the lowest ping time (latency) and lack of lost packets.  You'll find the channel with the least interference and should be good to go.  Just remember that channel 6 is usually the worst as it seems most cordless 2.4gig phones default to that channel.

Well, I'm using a Mac and it looks like that source is a PC program.

Well, since it seems to have solved itself, I think I'll leave everything alone for now! :smileyvery-happy:

 

I'm wondering why the Windows laptop didn't seem to be affected, unless it was the specific location of the Mac computer.

 

Here's what I was getting last night:

I discussed the issue with a tech collegue at school tonight.  It's clear that the problem was the Mac's inability to properly lock on to the wireless signal, probably due to outside interference.  The computer is against an outside wall and it's likely that I was having problems due to other signals.  What was interesting was that the Airport kept scanning for networks, even though it was supposedly connected.

 

Anyway, I think I solved the problem and I thank everyone here for their good suggestions!
