x120e WiFi Connection Speed - is 802.11n speed possible?

Dear guru!

 

Could you please tell me what should I do in order to get 802.11n connection speed on my new x120e? The better speed I get is 65Mbs. On T500 I get 300Mbs with the same WiFi access point (so it definitelly depends on notebokk but not the infrastructure).

 

Thanks in advance,

Vadim

Hi vlotarev!

 

Does your X120e have this Realtek wireless card?

Is the signal strength the same on both laptops?

To be honest, unless you have some super crazy fast Internet, it's not like the difference matters (unless your are transfering files over the LAN in which case it would be significant).

 

But for regular internet browsing and downloading, 65Mbps is plenty.

 

If the above driver updates don't fix it, you might have to mess with your router and change the radio band.

I had the same issue - constantly 52-65 Mbps, depending on position with the built-in Realtek card.

My wife has the Sony Vaio YB and it is constantly at 95 Mbps - I personally feel a slight difference in how fast the web pages are built up, but its not really an issue.

What I did finally (to satisfy my winner instinct :-), I exchanged the Realtek with a 2x2 Thinkpad a/b/g/n card, and it is working fine. Get now constantly 104-130 Mbps, so exactly double speed. :-)

Check if your router has a Channel Width selection. Mine was defaulted on 20mhz, which yielded crap performance, after changing to 40mhz it works as good as it can on this 1x1 card and connects at 150mbps to the router where before it was 72mbps.

Thanks everybody for the answers! I have "ThinkPad 1x1 11b/g/n Wireless LAN PCI Express Half Mini Card Adapter". This is 1 chanel card (I guess similar to Realtek) so maximum speed I can have is 150 mbps ... Thanks for the hint concerning Channel Width - I hope this would help.

Yeah the 1x1 Wifi card in the x120e uses a Realtek chipset, aka low end, Wireless N-Lite, 150mbps...

What really bothered me though, that this is not disclosed on the ordering page, its not even explained what the 1x1 or 2x2 mean, or what the speeds are...

Re: x120e WiFi Connection Speed - is 802.11n speed possible?

Yeah, I have issue with the description of the wifi options. I run a 5ghz N wireless network at home. I saw the base card supported 802.11 a/b/g/n so I figured Ishould be good. When I got the X120e, I was wondering why I didn't see it on my list of available networks. Arggh, no 5ghz support. I would have gladly upgraded if I would have known. Now I can't even find the broadcom 2x2 card anywhere.

Yeah, had I known (or bothered to research) what 1x1 and 2x2 meant I surely would have ordered the 2x2 card. The only difference between them was 1x1 was b/g/n and 2x2 was a/b/g/n.

 

Since i dont have an "a" capable router I didnt care for it.
