Question about Computers & Internet

4 Answers

I have an old thinkpad laptop that for some reason only connects at 11mbps instead of 54mbps when an usb wifi adapter is connected. (I have same model, another one which does not have this problem.) I want to surf/connect at 54mbps. The old pcmcia to usb 2.0 adapter does not seem to fit in the slots either (bent pins?) What are my options here? Can I connect a parallel jack on that back of laptop to a usb connector,then go from here somehow to somehow swich the usb port to 2.0 speed. Or perhaps serial port to usb 2.0 (a cable/adapter) anything is worth trying as long as not too expensive. Please do not suggest to resolder joints on board. I have a parallel cord here that I can strip one end of the cable and hook a usb cable to it if you explain which wire goes where if you think this may work.

    please read all my notes , previous 'solutions'?
    This is the deal, am using a 1000mw usb wifi adapter similar to specs to alfa 1000mw; only with this Particular Laptop does it connect at 11Mbps, not 54mbps as all my other thinkpads, all the exact same model do not have this problem.
    Also am using long extensions of reg usb extension cord. Using the entire long extension cord(usb) with This particular Laptop does not even allow the laptop to see any networks at all (won't work, power loss too much?) If I shorten the cord 6 ft, it connects at 11mbps, unlike all the other thinkpads (the same model w the same specs+ ram) which I am able to use the full usb extension cord with no problem and surf at 54Mbps all the time this showing in system tray.
    However if I use a very short usb cord to connect the laptop to the 1000mw usb wifi adapter, it still Connects At 11 Mbps.
    Using the parallel port to a usb adapter or serial port to usb adapter: is it possible that this may solve the problem?
    By the way, on the first expert's note about using a pcmcia card to usb 2.0 adapter, I Have Used this with a different brand (dell) laptop that had only 1.0 usb ports, and yes it worked perfectly.
    I have mentioned that the pcmcia jacks on this particular laptop seem to be bent, cannot fit the pcmcia card in either top or bottom.

    Hi Thanks for your advice. How does this device connect to the t40 thinkpad; it there a cable I need to buy as well in order to use this? Are you 80% sure at least this will do the trick?
    Please explain how this works, where it draws power from and why you are sure the usb's will function as 2.0 (54Mbps)?
    Thank you.


  • JOE May 03, 2010

    I don't see any legacy option/advances settings in bios,; I went through every option. If I use serial port to usb adapter, will the speed of usb be 2.0 (or you are not sure)?
    What do you think of the fixya tech who suggested I get a thinkpad port replicator 2 for the t40, this item is vey inexpensive. Do you think that is the best option (have tried removing all usb devices in dev mgr, etc, this has to be a board issue): if I take the hdrive out of the laptop w the 11Mbps, place it in another of same exact type t40, it connects at 54Mbps, so this is not a software issue, follow? Please get back to me.

You can use those cable converter but it is not effective because in old wifi version there is limit on speed .
In wireless 11 mbps is limit in old usb adapter and wireless module.
If you have same model gives this 54 mbps speed then you can get this speed on that usb adapter too.
For that uninstall all usb drivers.
Go to device manager then uninstall.
If you need serial adapter then try with that too.
Then check .
Also reinstall your wireless usb drivers after uninstalling it.
Let me know if you need further assistance.
Thanks for using FixYa.

  • Enable usb legacy 2.0 option in bios.
    For that when you power up the computer press F1 or F2 or del or ALT+F2 then you can see bios then go to advanced and enable usb 2.0 then save settings and exit.
    Buy new adapter for serial to usb converter then install driver then it will works.
    Let me know if you need further assistance.
    Thanks for using FixYa.

    ok, I get your situation properly now. The only viable solution for you is to use the ThinkPad Port Replicator II here
    you will have more than just the USB 2 ports.
    Regards


  • Muzahura Frank May 03, 2010

    you can get it as low as $5 from many resellers e.g here.

  • Muzahura Frank May 10, 2010

    Sorry I couldn'yt get back to you intime, but what I gave above is the only perfect solution and since the replicator has USB2 ports, it will connect at higher speeds. Normally, it plugs in the slots you see under the laptop, it is easy to install and cheap on line. i gave you a link above.


    Regards

  • JOE May 16, 2010

    Well guess what I bought it and it did not solve the problem at all.
    Thanks!

Ok, your USB port, and your WiFi card cannot "DO" 54mbps. unfortunately. There is just NO way to do this, even if you could use another USB 2, WiFi card, and you could plug it in, the BIOS, wouldn't allow it to work, as it doesn't "Know" 54mbps. The "Band width" of your system simply is NOT enough to process the data at any rate, IF you had onboard USB 2, then it would, BUT there is NO WAY again to effect this, even adding a USB 2 PCMCIA, PORT, or WiFi Modem, most likely will not work, but really is your ONLY shot, it may work, possibly, although I suspect it too, will default to 11mbps. You can do anything you like, it is simply NOT possible with you USB level, and inbuilt, WiFi & BIOS. So as related unfortunately, unless PFCMCIA works, then, there is simply NO WAY. IF you want a higher speed on the WiFi, then possibly, connecting to a Router via, the Ethernet, 100mbps, may help, but there too, you are limited by your Ethernet port, which, has a limited maximum, speed, 10mbps, too. I fear you are stuck, with what you have...

No wifi


The Fujitsu Lifebook S5582 does not have an integrated Wireless network card. This laptop was manufactured in 2001-2002. The integrated Wifi card was not generaly common in laptop computers until 2004.

So, you will need to buy a wireless adapter if you want to have wifi connectivity. Since this laptop is quite old, I would recommend a PCMCIA (a.k.a. PC card) adapter instead of a USB because it will be much lighter on the processor load.

You also have to be aware that using a wireless card will use more battery power and therefore shorten the expected autonomy of the laptop when running on battery.

Wireless


you may struggle if youve got win 95 on it, and only if you got usb ports,go for a wireless usb adapter if you can find one, as sometimes the pcmcia driver can be a bit fiddly and cause problems with pcmcia wireless cards. Although there are win 95 expansion cards available most are only 11MBPS transfer speeds as apposed to the 54MBPS and 108MBPS cards now available for other operating systems
