Change wireless card

  raysophie 13:53 02 Jan 09

I have a Dell Inspiron 1100 with a BT voyager 1020 wireless card, this gives a transfer rate of 11mbs, my desktop gives a speed of 54mbs on wireless. Would ther be any advantage of changing the BT Voyager card to one which will handle greater speeds ie. 54mbs I only use for general internet browsing and emails when the grand children are using desktop

I don’t believe you can change the wireless card on the Dell 1100

Just disable the dell card and install a PCMCIA wireless card

Go to Maplin with the laptop and check the wide range of PCMCIA wireless adapters available

you must get the correct PCMCIA wireless card that will fit the PCMCIA slot on your laptop

Buying on line can be a problem as there is difference type and size available these days

Sorry forgot to say that the wireless card is PCMCIA plugged into laptop, there is not a card inside.

In which case replace it as recommended by ambra4.

My question really was would there be any noticable improvment achived by changing the card

  ambra4 16:22 02 Jan 09

Yes the speed would improve from 11Mbps to 45 Mbps, and also the signal quality using a

present day wireless card

Your knowledge is much greater than mine, but wouldn't the speed of raysophie's internet browsing and emails (the computer's main use, apparently) be limited by the broadband connection speed?

If the b/b speed is only, say, 4Mbps, then will the wireless upgrade make any difference?

“If the b/b speed is only, say, 4Mbps, then will the wireless upgrade make any difference?”

The broadband speed has nothing to do with the wireless connect speed between the wireless

router and the wireless card the older wireless cards was 80.11B class and will only connect at

11Mbps even if you have the latest 80.11B/G/Draft N class router

The new wireless cards use 80.11B/G /Draft N class

Using an 80.11B 11Mbps wireless card with an 80.11B/G/draft N class router will still only

connect at 11Mbps

Using a new 80.11B/G/Draft N class router with a the new card 80.11B/G/Draft N class wireless

Card will connect at 54Mbps

There is also high-speed wireless router systems that will allow higher connect speeds at

108Mbps, 125Mbps, 300Mbps but these is made by difference manufacture and require that you

also buy a separate 108Mbps, 125Mbps, 300Mbps USB adapter or PCI card from the same

manufacture as the router for each wireless device you want to connect at that speed.

So connecting an 80.11B wireless card will still only connect at 11Mbps no matter what class or

speed of the router

Yes, I understand that raysohpie can considerably increase the data transfer speed between the router and the computer. But I got the impression that the question was - would this increase the speed of internet browsing and email.

So it seems to me that if the existing 802.11b wireless connection is faster than the broadband connection, then upgrading the wireless connection won't actually increase internet browsing or emailing.

Have I misunderstood?

Upgrading from 802.11b, to an 802.11b/g network card you should notice faster file sharing,

printing and faster internet access to web pages

In other words let me put it a another way


IEEE expanded on the original 802.11 standard in July 1999, creating the 802.11b specification.

802.11b supports bandwidth up to 11 Mbps, comparable to traditional 10Mbps Ethernet connection at that time

802.11b uses the same unregulated radio signaling frequency (2.4 GHz) as the original 802.11 standard.

Pros of 802.11b - lowest cost; signal range is good and not easily obstructed

Cons of 802.11b - slowest maximum speed; home appliances may interfere on the unregulated frequency band


In 2002 and 2003, WLAN products supporting a newer standard called 802.11g emerged on the market.

802.11g attempts to combine the best of both 802.11a and 802.11b.

802.11g supports bandwidth up to 54 Mbps, and it uses the 2.4 Ghz frequencies for greater range.

802.11g is backwards compatible with 802.11b, meaning that 802.11g access points will work with 802.11b wireless network adapters and vice versa.

Pros of 802.11g - fast maximum speed; signal range is good and not easily obstructed

Cons of 802.11g - costs more than 802.11b; appliances may interfere on the unregulated signal frequency

Definition of Bandwidth in computer networking refers to the data rate supported by a network connection or interface.

One most commonly expresses bandwidth in terms of bits per second (bps).

Bandwidth represents the capacity of the connection.

The greater the capacity, the more likely that greater performance will follow, though overall

performance also depends on other factors, such as latency.

Also Known As: Throughput


A V.90 modem supports a maximum theoretical bandwidth of 56 Kbps.

Fast Ethernet supports a theoretical maximum bandwidth of 1000 Mbps. (Or 1 Gigabit)

Wireless 802.11a supports a theoretical maximum bandwidth of 2 Mbps

Wireless 802.11b supports a theoretical maximum bandwidth of 11 Mbps

Wireless 802.11g supports a theoretical maximum bandwidth of 54 Mbps
