Default [Q] Wifi n 300mbps problem

Hi,
I try to connect my z2 tablet to 2 different routers which deliver a "300Mbps" signal (150mbps in fact, verified with a PC).
The maximum speed connection is limited to 75mbps on the tablet (which is very close from the router).

We can see : "Wi-Fi 802.11 a/b/g/n/ac, Wi-Fi Direct, dual-band, DLNA, Wi-Fi hotspot" in the specifications, is there something that i don't understand ?

Thanks

I have the same issue with mine. I haven't tried changing any router channels or settings yet. Using my galaxy s5 and Z2 tablet from the same location I get around 270mbps on the s5 and only 75 on the Z2.

Dual-band means: 2.4 GHz as well as 5Ghz Wifi. (Either / or, not at the same time.)

In any case the Wifi is restricted to 150 mbps.

Go into your router settings and look for a setting called "HT 20/40 Coexistence" and disable it (in dlink routers it's in Advanced > Advanced wireless). This worked for me when I had a similar issue.

I've tried before and it's not the solution. My wifi network is on the 40mhz frequency and i can have 150 mbps on a pc but still 75mbps on with the z2.

Actually now I just tested my z2 tablet's wifi speed, and it doesn't seem to go above 56 Mb/s (link speed for the connection in wifi settings is rated at 72 Mb/s), on my PC I reach my ISP's advertised 120 Mb/s. Odd stuff.

I found out that the tablet is unable to get above 72mbps link speed on a 2.4 GHz signal. When using a 5 GHz signal, the link speed leaps to 135 mbps (with a floor/ceiling between the access point and tablet). Maybe for some reason the tablet is unable to use the 40 MHz channel with 2.4 GHz?
