WiFi/Internet Speed and Strength Question
Hey all,
I've got a bit of a curious instance occurring with my WiFi and Internet through my Time Capsule. First off, I know I should have 105 Mbps internet speed from my service provider. I've tried to check this by connecting my MacBook into their modem via Ethernet, but I am unable to connect to the internet at all in this case. My MacBook instead says it has a self-assigned IP address and can't connect to the internet in the Network System Preferences pane. However, connecting my Mac to my Time Capsule via Ethernet does let me connect, and I've found this way I have around 81 Mbps download, and 15 Mbps upload.
Now, when I disconnect the Ethernet and connect to the Time Capsule over my WiFi network, while remaining right next to the TC, I find I have 18 Mbps download and 5 or so Mbps upload. My TC is model A1355, and should be able to generate 105 Mbps download speed from what I've read. My question is why is my WiFi connection speed so much slower than the Ethernet connection, and then why might I even then still be getting 30 Mbps less than what I am paying for each month? Could my TC be too old to handle the better speeds in reality, even though the specs for it say it should be able to?
Also, I have an old version of AirPort Utility yet on another computer, and in this version it was possible to change the Transmit Rate of my WiFi network being generated from the TC. I originally had the power set to 10%, but even going back and changing it to 100% did nothing for my internet speeds. In fact, I noticed my speed was slower at 100% transmit rate than at 10%. Is this setting even worth using anymore, seeing as Apple does not have anything like it in the new (10.10.3) Airport Utility?
Thanks in advance,
