Hello. I just configured my router and my macbook's internet speed is so low..
My max download speed is 4-5 mb/s and I tried on my friend's Lenovo laptop and his download speed is 8-10 mb/s

Why is my macbook internet speed so low ? :/

2012 Macbook has 802.11n wifi which is limited to 450mbps which would give 4-5mb/sec down load. Its going full speed so not slow ;-)

450Mbps would be around 45MB/s. As a rough rule of thumb between Mb/MB, divide the Mb by 10. 802.11n easily hits 40MB/s.

OP: ensure that the router’s wireless encryption is set to WPA2-PSK/WPA2-AES only, no mixed/legacy mode, and that your MBP is connected on the 5GHz band (if the router supports it).
[doublepost=1509283017][/doublepost]OP: also reset your PRAM if the earlier suggestions don’t work and ensure you restart your Mac with reopen windows when logging back in unchecked.

I have TP- link TL-WR740N and it's WPA2-PSK/WPA2-AES and I did reset the PRAM.. It's stuck at 4.9mb/s
Maybe the router is not powerful enough ? :/ Or it's something with my mac?
[doublepost=1509293505][/doublepost]I used speed test on my mac and my friend's lenovo.

On my mac i have 30 mb/s download speed 15 mb/s upload speed
On lenovo 70 mb/s down 40 mb/s up speed

why??

Is your screen facing toward or away from the access point? People sometimes balk at me when I mention how much the aluminum body itself impedes the signal, but I can get a 10+ Mbps difference by facing my screen toward the access point than if it is to its back.

That can also make the differerence of being connected to 2.4 or 5 GHz.

I would hold down the option key and click on the WiFi Icon in the menu bar
It should give you a drop down populated with how your MacBook is connecting to your router
Something in Security, Channel Bandwidth, PHY Mode is different between the two PC's

Try the speed test with Bluetooth turned off. Bluetooth often interferes with the WiFi signals in the MBP.
