USB Vs Express card wireless adapters

by c.sreenath / January 15, 2009 3:36 AM PST


I have a hp tx1219us tablet pc which is having trouble with its wireless functionality. Instead of spending more than $150 on purchasing an extended warranty and repairs, I want to use a wireless adapter.

Now the question I have is :

What are the main differences between a USB 2.0 wifi adapter and an Express Card wifi adapter? Is one preferred over the other? Why?

USB is not conducive to reliability. Get the express card.

USB is what I use when I have no other choice.

Same advice as above, but for a different reason. USB has become too popular for its own good. I have worked on PC's that were having operational problems because the USB subsystem was overloaded. Unless you have VERY few USB devices and plan to add VERY few others, go with the express card.

How many is too many? Depends on what they are doing, but here's a rule of thumb: mouse, KB, printer, jumpdrive on USB if you must. Otherwise try to avoid using it (which you won't always be able to do).

Express card is faster

You will be better off with an express card. It has has a faster download/upload speed rate than a USB card. Its maximum throughput is 2.5 Gbps, compared to a USB card's 480 Mbps. You did not say if your pc had an express card slot or not. Because you will need an express card slot to use an express card or a pc card.

express card IS NOT faster

do your homework gene8: evdo transmits at best, 3.1 megabits/sec -
an old-*** 11b card can handle this with no problem - your connection is not going to be any faster - whichever device you choose. the only consideration should be what you think your probablity is of breaking (off) the device. check here for validation:

Express card every time
by Zouch / January 17, 2009 6:02 AM PST

go with the express card (assuming you have an express card slot - if not, go PCMCIA instead). In addition to the reasons given by the previous posters, with which I concur, the main reason for my recommendation is physical reliability and robustness. It's just too easy to knock out a USB NIC, or worse, if your USB port is on the back, pick up the PC and break it off. An express card or PCMCIA card plugs a couple of inches into the PC and only has the aerial (antenna for our US brethren) poking out so it's much better protected and the card slot connector is a better physical connection that a USB port.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
