Problem on Wifi n 300mbps network

berbar38 — Tue, 10 Jun 2014 00:07:26 GMT

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

disconnect your z2 and reconnect to the router as other devices have been connected for a longer period to the router so reconnect your device by deleting the connection and starting afresh

Thanks you for youre (fast) help but i've already done this with no results.

WLAN only 72 Mbps with 300 Mbps router

Hello,

I am experiencing some speed problems with my Z2. I have a router (Fritzbox) which has a 300 Mbps WLAN (my PC runs this speed with the box), but the Z2 only connects with 72 Mbps. I read, that is is even capable of 802.11ac, so I would expect to be bale to use 802.11n.

What is wrong or how can I set the phone to speed up the WLAN connection?

Thanks to everybody with a solution.

Peter

Did you try to change the router protocol to WPA2?

It might be hardware limitation,I think this has been seen on other devices.

Same like berbar. WPA2 set, other devices have 300 Mbps, Z2 only 72 Mbps.

I have this problem on my Z2 tablet as well as on my Acro S. I just got a brand new router aswell. Speed on my PC is fine.

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?

Hi all, I had the same problem. My router is capable of 500mbps. On my PC I am getting 450mbps on wifi but on the z2 it goes upto 72mbps only. I have tried with 3 routers, same behaviour. However with some digging in the settings I managed to understand why and now I get pretty decent speed of 390mbps on my current router and 150mbps on my older router. You have to go to wifi settings then Advance then disable Wifi optimisation. I think by default it is enabled. Note: you may notice a reduce battery usage time as the wifi will work at full power i guess, consuming more power. I have not used it a lot to see the real difference. I hope this helps.
