Does anybody know the Intel part no. for this IBM branded (link below) wireless lan PCI adapter?

Thanks

As far as I know that one has Atheros chipset, not Intel.

They show two on their website and I know one is an Intel. This (link below) is the other one. The one I want to purchases is an Intel WM3B2915ABGNA. I think that the same as the IBM branded chipset but I wanted to be sure before ordering.

All I can tell you for sure is that the $65.00 one is the Atheros and it works very well. Received one a few weeks ago.

d lehmann:

Where did you buy it?

I guess he bought it from IBM US. Click jmt's first link.

I bought it direct from ibm for 68.00 including tax with free shipping, arriving in 2 days. It seems a little more powerful than my intel chip

Are you looking for the Intel 2200 BG? or the Atheros A/B/G? If the Atheros - then model I or model II?

Atheros 802.11 abg model 1 or 2? I thought the Atheros card was designated
a CM-9....that's what is on the pcb. The atheros chip (visible) is an AR-5213A. I believe part of the 5004 chipset?

What are the differences between a 1 and a 2?

Thanks!

Greg,
Since last we spoke - I found that there are two models of the Atheros mini-pci card. I have model I (FRU 91P7301 which is the same as 31P9701). You may as well. Check out the IBM site and you will find there are two listed.

Also I found that the Intel 2200 BG card does work without modification or patching needed.

Aparently the Atheros Model II works as well without patch.


Atheros Model II (US model apparently)

I bought my atheros card from a European reseller. I remember at one time that the 802.11a cards were being put through scrutiny by the FCC because of interference with RADAR aboard planes. Could this be the difference between the two cards?

The 73P4301 has an FRU number 93P4262.

I ordered it today at 58USD price in Hungary.

Finally, something Europeans can get cheaper than Americans!

The mini-pci card that I have is:

FRU 91P7301 Philips

The funny thing is - it won't work in an HP nc6000 either. Similar message - BIOS Error 104 Unsupported mini-pci card.

I have a T41 with an internal wireless 802.11b. Recently, I bought and installed the new compact Linksys router (54GC).

I'm thinking of purchasing and upgrading to a "IBM 11a/b/g Wireless LAN Mini PCI Adapter II" ($65). It would probably give me a faster connecting speed than 11mbps. (closer to 54mbps??) As well, it'd allow me to use 802.11g. (which I've heard gives you greater range/faster speed)

Now I have a question. When it comes to how fast you can surft the net and download files, is it the "speed" (mbps) that matters most or the "signal strength"?? Because I'm getting
a fairly low signal strength, when I move the laptop to the basement. The speed also occasionally drops from 11mbps to 5.5mbps. But still a relatively good speed in downloading most web-pages.

What about 802.11a? Does anyone mainly use this? (are there any benefits or advantages? I'm thinking this "might" be useful to me, since I have 2.4ghz phone and microwave adjacent to the study room where the computer/modem/router are located.) Though for this, you'd need the A+G router. (or an a/b/g)

I'm told that you would need to download a driver in installing the a/b/g Mini PCI Adapter. After that, are you given any instructions as to how to begin and complete the adapter installation?

I never measured the transfer speed on my wlan, but now I can transfer files about 2500Kbyte/s between my T41 and my desktop Pc.

IBM 73P...... a/b/g wlan as I described above and USR8054 wlan router.

Unfortunately my ADSL is only 1536kbit/s.

Don't worry, our beloved ISP is going to double the (download) speed until May 15th.

Due to lack of responses on topic...

I've also had the Intel 2100b long time ago, my reasons for upgrading to Intel 2200bg (costed me around US $30 at the time) were:
* I needed to copy large files over the home network (from the home desktop PC to my laptop)
* I wanted to watch the MPEG-2 stream in the real-time on my laptop (had a TV-tuner installed in the desktop and wanted to watch TV live on my laptop over my network -- the 802.11b wasn't fast enought for that)

I know there're options for a faster than 802.11b internet connections in the States, but for an average ADSL/Cable, your 802.11b connection to the router is usually times faster than your internet connection, so I don't think you'd gain any speed on loading web-pages.

You're right on noting that 802.11a is more resistant to interferences from your 2.4Ghz home electronics and microwave. And yes, you will need an 802.11a-compatible access point/router for that.

PS. From what I've read the Intel 2915abg offers better power consumption/savings than the Intel 2200bg. Not sure about that tho, don't even remember where did I read that.
