You mentioned that your MacBook Pro seems fine connected wirelessly when close to the router, but not when "quite far away."
As you can imagine, not all Mac models use the same antenna or have the antenna placed in the same location within the body of the laptop.
It sounds like the signal quality from the wireless router is just not adequate enough to provide enough bandwidth to your MacBook Pro. One way to measure signal quality is to calculate the Signal-to-Noise Ratio (SNR) of the router at the locations you typically use your MBP. You will want the SNR value to be 25+ dB at these locations to get decent bandwidth.
Thanks for such a detailed response. My signal/noise is
Signal / Noise: -76 dBm / -94 dBm SNR = -76 - (-94) = 18
Transmit Rate: 24
Signal / Noise: -81 dBm / -88 dBm SNR = -81 - (-88) = 7
Transmit Rate: 18
I am unable to move the router or my workspace so what would you suggest? Would an 'n' enabled router help?
Before investing in another router, I would take your MBP to different locations where you can connect to other Wi-Fis. Do the same SNR calulations that these locations to get an idea on how your MBP's wireless performs. If you see definitive improvement, getting a new router for your network may well be worth it. If not, then there may be something amiss with the MBP and a trip to the Apple Store would be warranted.
How rude of me! I was just popping back to this thread to see about transmit rate values and realise I didn't respond.
I put the signal booster half way between my router and my Mac which was at the top of the house.
Worked good for a while (S/N was hovering around 15-25) but recently (unsure of the reason) it has been much slower. Just before calling the ISP I tried putting the signal booster in the same room as my Mac. Now I have...
Signal / Noise: -61 dBm / -91 dBm
Transmit Rate: 54
This was only 10 minutes ago but it seems good. I have no idea why I didn't do this earlier!
That was an excellent suggestion. My MacBook Pro is running slow. With your suggestion I was able to determine that I had a low signal. Plus, I learned alot. Very helpful.
I am going to assume that the low signal is the source of my problem. I have done lots of cleanup etc., so I think I am ok on that end.
