I'm trying to configure a home server, but the connection is very unstable. I looked at the WLAN adapter's (USB) settings and found out that the speed never goes above 72 Mbps (I mean Mbps not MB/s). On the box of this adapter is written "300 Mbps USB WLAN adapter". On the box of the router is written "150 Mbps" and my laptop (also my sister's and my dad's laptops and my mom's PC) is with 150 Mbps. However, when I took a look on them the speed never goes above 68 Mbps. I'm wondering if the problem could be in the router, because I turned off all the devices in the network and the speed remains the same?
Several reasons why the speed is limited to 68/72 Mbps.
Somethings you can try.
a. Try connecting the laptop directly to the router using a cable and see what the performance is. That can eliminate point 3 as the cause if you can get faster speeds.
b. Try bringing the laptop next to the router to see if the speed increases. That can clarify if point 2 is playing a part.
c. Try a different router of better quality. Of course this will not give 150 Mbps but might improve. If you ask me for 150 Mbps router, 72 Mbps is pretty good.
d. Better yet, get a faster router (not just better quality, but that supports upto 300 Mbps). This is only if you want higher speeds.
