Airport Extreme is Fast with Ethernet, Horribly Slow with Wireless

I have an Airport Extreme router that worked great for a couple of years.

These days, the wireless connections are unbearably SLOW. I've updated the firmware, I've restarted, I've tried all different channels, I've tried removing the security and starting over with the original settings. Still slow.

A page that loads in about 3 seconds with my wired connection takes about 23 seconds using the wireless.

It doesn't appear to be the wireless car in my Macbook, because it performs fine when on other networks.

Do these things just go bad after a while? If it does "go bad," does it make sense that it would continue to work, only at a slow speed? Does it make sense that the ethernet ports continue to work properly.

And, is there anything I can do about this? This slow connection is really unbearable.

Thanks!

It is possible in older hardware for the timing crystals to lose their resonance, and as such the network speed you could achieve would be reduced because it would have to find a time harmonic that matched the data transfer rates.

Generally these tend to be a bit older though, or it may be a defective timing crystal in your router.  Other things that could be interferring could include hands-free phones operating in the same frequency range, or someone in your area with out-of-band ham radio.
Just chk if anyone else in your surroundings also wireless infrastructure configured on the same channel..becoz interference also may cause a degradation in the performance....

Have you tried activating interference robustness in your Airport Extreme or changing the wireless channels? It is probably set to channel 1, 6 or 11 by default, which are the most common channels and most likely to suffer from interference.

• If you updated firmware and reset the device to the factory default and still have problem with wireless connection speed I would suggest to get another wireless router. It does not have to be apple device.
e.g D-Link -DIR-628

Personally I wouldn't be buying a DLink of anything anymore.  I have had a number of devices that cause me issues over the years.

I agree with EG777.  Get a new router.  If you don't like D-Link, get a Linksys.  It sounds like you have tried all of the proper fixes.  Unless there is another device interfering with the network, you should not be getting these very slow speeds.  I suggest a Linksys E1000 router.  It is very cheap and works very well.  Try newegg.com.  I hope this helps you.

Thanks, everyone, for their thoughts and input. I'm still stuck.

Originally, I had changed the channels and got nothing from that.  

I tried activating interference robustness, but that didn't work.

I also checked my RSSI and Transmit rates by option-clicking the  airport monitor on the top of the screen.. and those seemed satisfactory based on what I read about it.

I also checked using iStumbler to get readings on the noise and noise ration. All seemed good.

So…. I went out and bought a new router… a linksys this time around. It was all more of the same: ethernet connections work lightening fast, but the wireless connections are sluggish… all readings seem pretty good.

Any other thoughts?

Have you tried another system on the same network?

<<<< Have you tried another system on the same network? >>>>

Well, I use my iPhone on the same network is quite sluggish, too. That's the only other thing I've tried.

I also use my laptop on other wireless networks and it seems to work well.

• Have you installed the latest updates for your new Linksys router?
• If your computer works with other wireless networks I would try to use another wireless router again. (Linksys router might be bad as well)

Changing the DNS settings ended up fixing the problem. I had tried that at one point, but I guess acquiring the right number made the difference.
