2915ABG vs 2200BG

what are the differences??

 

The first one supports 802.11a the second one does not. That's the most notable difference. You probably don't need a if it's more expensive.

 

The 802.11a standard is not that widely used since it's not compatible with the B or G standards. The only reasons to get a card that supports A networks are to be compatible with an existing A network or if you just want full support for a just in case scenario. I'd just stick with the 2200BG card as the majority of the hotspots and routers in the market are B/G supported. If the 2915 doesn't cost you anymore that the 2100BG, you may just want to get the 2915 for maximum support.

oh..i am not sure whether it costed me or not
but thanks for the info

 

i saw ppl are having problem with connection speed in 2200bg. will the same problem most likely occur with 2915abg too?

I think you ment 2200BG not the 2100BG as 2100B has only B.

Yes, My friend is using the 2915abg and he is experiencing the same problem as many others using the 22000BG. I'm using the 2200BG myself and have the latest drivers and havent encounted problems yet. (My problem is speed drop where as others is consistance disconnection)

Intel Pro Wireless 2200BG (Driver Vers. 9.0.2.1 Currently Unavailable to the public)

 

X,

OOPS!!! You're right, it's the 2200BG.

-----------------------------------------------------------------------------------

That's a weird thing, I have the 2200BG and have not noticed any problems with speed or dropped connections. Does this only happen in G mode or also in B as my router is an SMC B router. I also use the lastest drivers from Intel's site and have never experienced any problems with mine either. I should be getting a G router tomorrow, so I can give that a test and see what happens. Will report back in a few days after testing.

[Edit] Router currently out of stock, but will ship when available. Will report back after I get the router.

In the other thread people have been saying that its only when its a G connection. I have a Netgear and it does both B and G. But when its only on the G it would stay connected to 54mbps. But when we include the B (so its doing both B&G) i find that the speed drops happening sometimes as low as 1mbps and i would be sitting in the same place. I dont know whats going on there but its a bit stupid that it happens that way. Anyways all the equipment in my house are G so its no big hassle of keeping it on G.

I myself have never experience disconnections only the speed drop. So i dont know about that one.

 

The speed drop may happen if a B card jumps onto the network while you're in B+G mode. Try changing to just G and see what happens.

Also, I just picked up the new router today ($25CDN after rebate) and it also came with a USB 2.0 G adapter as well. I'll be trying the router out in the next few days, so I should be able to see if it drops or not.

Ok, I'm currently on the notebook connected to the new G Trendnet router and it does seem that I also get a speed drop from 54Mbits to 1Mbit. I does seem like a Power Management setup of the card/drivers. I believe I remember reading that it takes more power to maintain a 54Mbit connection than it does for an 11Mbit, so dropping it to 1Mbit is going to an extreme, but it sounds like a good idea. Since most highspeed internet connections are approx 3Mbits and up, I guess you're not really gonna notice too much of a difference when data starts transfering again.

I have not note connection since starting (currently only 30mins into the testing). Below is my current setup:

Intel 2200BG WiFi w/Intel 9.0.2.25 drivers from Intel site (using Win Zero Config)
Card setup with WPA-PSK (TKIP)
Intel Enhanced Throughput = Enabled
Mixed Mode Protection = Default (CTS-to-Self enabled
Power Management = Highest
Prefered Band = Default (G band)
Transmit Power = Default (Highest)
Wireless Mode = G Only

With this setup, I have not lost connection yet. I have the G router connected to my wireless B router via cable (daisy chained so I can get internet to G router).

I'm currently approx 40ft from the router, in a different part of the house (same level).

I will report back with an update after further testing.

[Update]

I have replaced the router with a new SMC G router as well as upgraded the drivers. As it turned out, using Intel's EXE to update the drivers didn't seem to do the job, so I was still using the older drivers. After replacing the drivers to 9.0.2.25, I was capable of keeping a 54Mbits connection for a hour or so before it dropped to 48Mbits for a few hours (running a battery drain test). It's possible the test was the cause of the speed drop to save power. The connection has been stable and has not dropped connection once.
