Surface Pro 2 wifi issues

I really don't know what was in Microsoft's mind to add this stupid Marvell Avastar 350N wifi card to the Surface 2 Pro. Even though it's called 350N the best speed you can get is 130Mbps with the Bluetooth turned off. If the bluetooth stays on it's 65Mbps. I had a lot of issues connecting and using it simultaneously with bluetooth headset, connecting to my work guest network via WPA2 Enterprise. At the moment with latest Windows 10 I cannot connect to the work guest network at all. I mean this would be acceptable for 100 Eur netbook, it's not for a 1000 Eur hi-end machine. I feel stupid using an usb dongle in such an expensive machine. Connecting support just recommended to refresh the computer which did not help and I just spent several hours restoring applications.
Probably my next hybrid will be Lenovo or something else. No more Microsoft.

Sapido router RB 1132 review





















Because of temporary place of living in Helsinki I have to use a 3g net. It's nice that Finland is quite advanced at internet technologies and I could get a modem (huawei e1552) + 1month free net for 40 E, afterwards 20e for 1mbit or 30e for 3.6 mbit's.
So to share the net between my computers I decide to buy a new router which supports USB modems. After a small research I have chosen Sapido RB 1132. It's linux based (no hacks available jet), has wireless n and it is small. I bought it for 77$ on ebay (14 Eur Finlands VAT).
Installation was very easy except it was fun finding a option in Chinese language to change to English. After some basic configuration - WPA2 passphrase, DHCP scope everything started to work fine. So i will make a small review on functionality:
Interface seems very simple, easy and quick.
3G
A bit of surprise here, directly in PC 3g modem provides ~2mbit speed, through Sapido router - ~1mbit.
802.11n
Had not tested jet, none of my computers has n card.
802.11b
Everywhere in flat the speed is reasonable (from Ethernet) - ~2-3 megabytes/s
Ethernet
It's 100mbit/s not 1000, so if theoretically n network would work with 300mbits than connection to wired computer would still be 100mbits.
DHCP
It's a pitty that you can't use fixed leases together witch scope. Either one or another.

Conclusion
The router is ok for my needs but I really hope that 3g speed will increase with next firmware releases.
Edit 09.2010 Next firmware did not solve speed issues
