After reading many positive reviews online, I made the purchase of cisco E900 router.
But I'm not even getting 1/5th of performance promised in the product description.

I'm getting wifi range only in the room same as the router, even five feet outside the room and wifi is gone.

They promise speed of 300 Mbps over WLAN but when I try to copy paste a file from my desktop to laptop the speed barely reaches 1 Mbps.

Do I have faulty router or have I configured it incorrectly?

You have 2 things involved the router and your pc nic card. Either or both can have major impact on the connection so you really need something other devices to try to isolate the issue.

First you never even get close to those magic speed numbers. Maybe you could get 75m on a 300m connection. Then if both your laptop and desktop are connected via wireless they will compete for the bandwidth making it even worse. You should get well over 1m though.

Your problems are likely the standard interference issue. When every person living around you has at least 1 if not 2 or 3 routers all running wireless competing for the limited wireless bandwidth it is tough to get some to use for yourself.

All you can do is try the standard recommendation. Try other channels normally 1,6,11 are the best to try. Change the channel width to 20mhz. There is only 60mhz total in the 2.4g band and you are much more likely to be able to get 20mhz than 40mhz of signal that someone else is not trying to use.

Thank you for your reply.
I tried changing channels but it is more or less same thing.
I've got gigabyte z77x-ud3h it is only a year old.
My home has 7 inch thick concrete walls could this be reason for poor wifi range?

Concrete is one of the harder things to get a wireless signal though. If it works well inside the room next to the router but you get low signal level outside the room then there is little you can do. You may be better off with a powerline network solution or if you are very lucky and have tv coax in both rooms you can use MoCA. If you need wireless in the remote room would use the powerline or moca devices to carry to that room and then plug a AP/router into it to provide the wireless.

You mean only way to make it work is to spend more money?
Where I live it really not feasible solution as hardware you are suggesting is rarely available or it is priced more than twice its price in US.

Thanks for your help though
