Abnormally reduced speed when using fiber optic over wifi

[xRush]

Hello.

Yesterday I got a 100Mb download/10Mb upload speed FTTH connection installed at home by the company's technicians. I'm getting the full 100Mb download speed when I go wired on any computer - however, when I go wireless, the speed is greatly reduced, never surpassing 18mbits.

I've done some tests and here are the results:

• 
  On my room's desktop PC (which is about 30ft away from the router), using TP-LINK TL-WN722N USB adapter (which complies with 802.11n and supports up to 150Mbps), I get 17-18Mbits
  
  On my Toshiba C70B laptop, with an integrated wifi adapter which has the same capabilities as the TP-LINK above, I get pretty much the same. This laptop has been tested at about 13ft from the router.
  
  On my Acer Aspire One D255 netbook, using the same TP-LINK Wi-Fi adapter as in the first test, at a distance of barely 2ft, I get about 17Mbps again.

All tests were done at speedtest.net using the closest server.

I get the same speed no matter how far I get from the router, so I don't think speed loss is caused by lack of wi-fi signal. Could it be the router? It's a Huawei HG8245H and it's the one that the company's technicians brought.

Hello xRush,

During wired transmission there are hardly any data loss. However, in wirless dat@ transfer their are so many things going around you, microwave, cellular data, radio tower nearby, police station, TV antenna and many more.

It can also be the fact that your router does not have a capability to transmit above 50Mbps or does not transmit at least 80mbps. For this you have to contact the router guys and tel them the situation.
Hopenthos helps ☺

Try a 5 GHz band, much less interference, provided your wifi card and router support it. I went from 4MBPS to the full whack 10MBPS when I upgraded mine.
