I'm getting a new to me iMac G4 17" 1.25GHz running Leopard. I've seen mixed reports that the AirPort Extreme may not work with my new Xfinity router. Is this true? If so what are my options for getting wifi?
Just letting everyone know the AirPort card works fine with the Xfinity routerI think it would work with the Xfinity. The 802.11b/g card should support TKIP and AES/CCMP. Unless the Xfinity router only uses WPA3, which I'd imagine is unlikely.
I’d think that an iMac G4 could only get so fast of an internet speed, so I think 23.57 Mbps is good.My wireless internet is painfully slow. I tried using a wi-fi extender and connected an ethernet cable to it and the iMac but the best I could do for speed was 23.57 Mbps. Any thoughts on what I can do for faster speeds?
Can you test a direct ethernet connection to the router?My wireless internet is painfully slow. I tried using a wi-fi extender and connected an ethernet cable to it and the iMac but the best I could do for speed was 23.57 Mbps. Any thoughts on what I can do for faster speeds?
I can't do a direct connection because the router is too far away. I bought a Netgear Powerline 1000 and connected it to my Mac Studio and got 1205.34 Mbps but when I connected it to the G4 iMac I only got 23.21 Mbps. I'm using speedtest.net to test the speed.Can you test a direct ethernet connection to the router?
Also, what are you using to test? If you're using a bandwidth check on some website, it's possible that all the scripts etc. running on it bog down the G4 so much that it affects the test results.
I have a 1.25GB G4 with 2 GB ram so it is maxed out. Is there a usb dongle I could use to increase the speed?I can't do a direct connection because the router is too far away.

I can't try speedtest.net on a G4 right now, but look at all the scripts running in the background that the G4 quite literally has to churn through:I'm using speedtest.net to test the speed.
You could try getting faster speeds by using a USB 2.0/3.0 toIs there a usb dongle I could use to increase the speed?
I used Interwebppc and Safari Webkit and got similar resultsOne issue that you have not discussed is the browser that you use for your test.
Working browsers can be a very real issue for PPCs and Leopard (or older).
Maybe the browser that you use is just not helping you...
802.11g Rated Speed
The rated speed of 802.11g networking devices is 54 Mbps. However, 802.11g and other Wi-Fi network protocols include a feature called dynamic rate scaling. When the wireless signal between two connected Wi-Fi devices is not strong, the connection cannot support the fastest speed. Instead, the Wi-Fi protocol reduces its maximum transmission speed to a lower number to maintain the connection.
It is common for 802.11g connections to run at 36 Mbps, 24 Mbps, or even lower. When dynamically set, these values become the new theoretical maximum speeds for that connection, which are even lower in practice because of the Wi-Fi protocol overhead.
You’re still limited by the speed of the iMac’s WiFi adapter (54 Mbps max), assuming you’re using this as a WiFi extender.I bought a Netgear Powerline 1000 […]
This makes sense that the wi-fi would work at a reduced speed but a direct connection with a Netgear Powerline to the ethernet port on the imac should be fasterIt's running about half of its maximum theoretical speed. A quick search back reveals this:
The Netgear Powerline works as a ethernet device over the power plug in the house.You’re still limited by the speed of the iMac’s WiFi adapter (54 Mbps max), assuming you’re using this as a WiFi extender.
Then the theoretical maximum is 100 Mbps minus some overhead. Have you gotten round to rechecking?The Netgear Powerline works as a ethernet device over the power plug in the house.
OP is using the Netgear Powerline 1000, which is Gigabit speeds. I do not use the Netgear devices, but I do use powerline devices and have been using them for a few years now.Then the theoretical maximum is 100 Mbps minus some overhead. Have you gotten round to rechecking?
Yes I did the test on both the iMac and the Mac Studio in the same room.OP is using the Netgear Powerline 1000, which is Gigabit speeds. I do not use the Netgear devices, but I do use powerline devices and have been using them for a few years now.
Mine are ZyXEL Gigabit and that's how I get Gigabit ethernet out to the garage. I have a Gigabit switch sitting on top of my garage door opener plugged into the receiver and the sending device is in the kitchen.
You'll never get the full speed over powerline, but it gets close.
OP, were your iMac and Mac Studio in the same room when you did the tests on the adapter?
