Transmit rate with time capsule

Question

Hi, sorry for my english.
I installed my time capsule yesterday,
it works with mbp 2009 in 5 ghz and have a wpa 2 security but the transmit rate never pass 162.
I understood that time capsule can get 300 mb speed so why i get only 162?
I also use ipad and iphone 4 that connected to the 2.4 ghz wireless of the time capsule
the mbp get transmit rate of 162 even if it in the same room with the time capsule, what i should do to make that the transmit rate on the mbp will be 300?

Answer 1

i noticed that this problem resolved if the MBP is closed to the TC, but if the MBP is in another room the transmit rate fall in 50%.
The issue is that the 5 GHz signal strength dissipates quickly with distance and does not traverse through objects (like walls) as well as those signals at the lower 2.4 GHz band.
if i will add to my network airport express in the another room it can help me to achieve the full transmit rate that i get in the room of the TC?
Potentially, but there is no guarantee. If your goal is to add the 802.11n AirPort Express Base Station (AXn) wirelessly, there will be some overhead required to maintain the extended network. This will reduce the overall bandwidth. In addition, the AXn would need to be within a strong enough signal range of the TC, in order to extend the 5 GHz radio as it would experience the same signal that your MBP gets now to attempt to extend.
Two options: 1) Connect the AXn by Ethernet, or if that isn't practical, 2) Consider using Powerline adapters. These take advantage of your home's electrical circuit to create a pseudo Ethernet one. You would then place one of these adapters at each router and connect them by Ethernet.
Both of these options remove the bandwidth loss for extending the wireless network wirelessly.
