Airport Extreme Freezes and Connection Slowness

Not even a year ago, we replaced our old Netgear Ethernet Router and old Airport Express with a nice, shiny, new Apple Airport Extreme. Lot's o' promise. The main problem (apart from other minor hiccups you'll find on here) has been that we typically have had to soft reset the unit daily, because the connection would become completely unresponsive--including Ethernet and wireless connections. So, it was either the cable modem (which worked fine with our old router) or the Airport Extreme, which judging from a Google search is giving more users than just me fits. So, I've played with all sorts of settings, including turning off IPv6 in the unit and on all the computers in the house; that didn't seem to fix anything.

However, I may have just made some changes that greatly improved my download speed while also eliminating the need to reset the AEBS each day! We'll see if my "fix" holds up. But the speed improvement is a plus.

First, I changed from "Automatic" to 100 Mbps/Full Duplex in the Airport Utility and restarted the AEBS:

Next, I changed similar settings in System Preferences->Network ("Automatic" to "Manually"):

Speeds via speedtest.net showed a dramatic improvement for download:

Then, I finally found the culprit: The automatic MTU!!
I couldn't believe it. Such a stupid, basic cause of such a big problem. This is most certainly a BUG.

To fix the MTU:

1. Apple Menu > System Preferences... then Network.

2. On the left, choose Ethernet , then Advanced... on the bottom.

3. Choose Ethernet tab:
. . . Configure: Change from Automatically to MANUALLY.
. . . MTU: Change from Standard to CUSTOM. Put 1452 then click OK. Then Apply at the bottom.

Extend New Airport Extreme With Old Airport Express

So maybe you're like me and bought a new Airport Extreme Base Station (802.11n) and want to extend your wireless network through an older Airport Express (802.11 b/g). After Googling this, I discovered I wasn't the only frustrated user. Apple wants you to buy a newer Airport Express with 802.11n to make extending your network easier. However, you can still use the older Airport Express with a little work and a hidden trick.

For some reason, this took me SEVERAL hours to figure out. It didn't JUST WORK. LOL! Fortunately, I learned that using the Option key while selecting the Wireless Mode popup menu in the Airport Utility (Version 5.5 (550.29)) returns to the user the ability to set up a WDS (wireless distribution system).

A nice user named Bob on the Apple Discussion forums confirmed the Option trick I had learned elsewhere. However, I still had trouble getting the WDS to work properly. Here's what I tried that seems to do the trick:

Thanks Bob. Yes, I found that trick elsewhere. Still had trouble, even though I went through all the proper motions (i.e., making the AEBS(n) the WDS base station and the APX the WDS remote...including entering the correct MAC addresses for each).

However, I think I've discovered the fix that allowed my old APX [Airport Express] to work with the new AEBS [Airport Extreme Base Station] in a WDS network: I set the radio mode on the APX to 802.11g ONLY! The radio mode on the base station was kept at AUTOMATIC. And I used Channel 1 for the 2.4 GHz frequency on both and left the 5 GHz frequency channel selection at AUTOMATIC on the base station. WDS wasn't working until I made those changes (don't know if one or more of those steps is important...but it's working now).

Slow iPhone YouTube Over WiFi Workaround

I discovered this problem on my iPhone too and it's annoying. Fix it Apple! Changing my Airport Express settings each time isn't an option.

Currently, the wireless network is set to G-Only since this was the best setup for our office. It was only when I switched the Wireless Network Mode to B-Only that YouTube videos began watchable again. None of the other settings had any effect.
