Thinkpad b/g/n wireless speed?

Well it seems as I made mistake when ordering or lenovos system changed my order and I didn't notice in time but somehow I wound up with the thinkpad b/g/n 1x1 card made by realtek instead of the intel card I thought I had ordered. Anyway I can't seem to get this card to connect at anything over 72 maps on my wireless n network. I've tried every thing I can think of settings wise 20/40mhz/wpa2-aes but just can't get 150 mbps connection even if im right next to the router. Anyone out the have this wireless card getting over 72 mbps link with it? Would be pretty frustrating if that's the max considering the intel card was supposed to be a free upgrade. Any help would be greatly appreciated.

 

other networks around you may create interference with your network, thus the lower speeds (no matter how close you are to the router)

on my network I had to chose only one channel of use - the highest, as I got 10 - 15 other networks around, so both of our laptops connect at 130mbps, though I've seen 142 from time to time (WPA2/psk). Try that.

we got intel 4965N on both though.

 

Keep in mind that there are only three non overlapping channels. 1, 6, 11

The other channels interfere and are not true seperate channels. So if you see a lot of APs using Channel 1 switch to 6. If you see them using 6 switch to 11, etc etc..

 

Only if you transfer a lot of files over the network will it make any difference, at which point USB might be a better option. Maybe you want to see how it goes before you decide it's bad. At some point in the not too distant future, you'll probably be able to buy a ThinkPad WiFi card on eBay fairly reasonably if you want to upgrade.

 

Most of the good intel cards can be found on ebay for like under $40, so that's always an option if you don't like this one. I actually did the same thing you did.. but to me as long as I can connect to campus WiFi I won't complain.

 

Yeah im using inssider to chose the least occupied channel which is 6 in my area. Only one other AP on that channel and its pretty weak. I just assumed i should be able to get at least a 150 mbps link in windows wireless even if thats not gonna be the true throughput. Realteks website indicates the chip can do 150mbps on the 40mhz band but i cant find any place to activate that band in the wireless adapter settings. Maybe the card is just too new and the drivers arent mature enough idk. And im not sure upgrading the card is possible due to the antenna situations 1x1 realtek vs 1x2 intel but i really havent gotten that far.

Its not the end of the world though I've tested the true throughput via file transfers over the wlan and its a respectable 5MB/s or about 40mb/s. I can live with that its just that ive got this new N router and this is my first N device other than smart phones so i was hoping to be a little more impressed. lol
Just seems strange that there is no clarification of what this adapters throughput is capable of from lenovo and why they would even offer an inferior/slower card with no benefits(if it is truly inferior) for the same price. Who would willingly chose a slower adapter for the same price? lol Anyway just kinda hoping someone else had this model card and was gonna tell me they get 150 mbps with it.
