The wifi is going 54 mbps but should be 100 mbps all cords are plugged-in properly what do i do?

the bandwidth that connects might not allow or be capable of any more mbs per second or the network is overloaded you can test your bandwidth just click on the link
you could try to speed up your bandwidth im not sure how it works or if its worth it
hope this helps

hi

the T42 does not have WiFi, instead it facilitates internet connection via 16 BIT & 32 Bit PCMCIA slot to install a WiFi card , in order to go on the internet.

The ThinkPad uses the following adapters: v 360, 365X, 380, 600: 16-Bit PCMCIA v T20, T22, T23: 32-Bit CardBus and MiniPCI v T23: 32-Bit CardBus and MiniPCI Daughter Card v T30: 32-Bit CardBus and LAN on Planar Board (LOB) v T4x: 32-Bit CardBus and LAN on Planar Board (LOB). 16- and 32-Bit PC Card adapters are configured during ThinkPad initialization. Network Interface Controller data rates are: v For Token Ring: 4/16 MBps v For Ethernet: 10 Mbps...........16 bit PCMCIA 10/100 Mbps.......32 bit CardBus 10/100 Mbps.......MiniPCI and Daughter Card 10/100 Mbps.......T3x and T40 LOB 10/100/1000 Mbps..T42 LOB The MiniPCI Ethernet adapter is accessed behind a removable plate located on the bottom of the ThinkPad directly above the Model/Type S/N sticker. For T20 and T22, the MiniPCI adapter may be an Ethernet/Modem combination card. The Daughter Card (T23) is secured with two screws and is located next to the MiniPCI modem adapter.
please go to this link to read the manual -- it will explain the features for this ThinkPad of various series T42 model-type .

Wireless Ethernet (802.11a or b or g) does not get the bandwidth you would get through a cabled connection. My guess is that you have an 802.11g network card in your computer and 54 Mbps is the top theoretical speed for that type of Wireless adapter. Cabled connections will give you the theoretical throughput of 100 Mbps. Also, since this Linksys device is not a Wireless access point but simply a switch, your computer doesn't actually connect to it. Most likely you are connecting to your cable or DSL modem. Most of these have a wireless radio built in.

Wi if is the slowest form of connection and is shared with other devices. If you want good bandwidth you need to connect via ethernet cable directly to the router.
Examlpe... wi if 4 meg shared, Ethernet 100 meg..
good luck !

100mbps is just the maximum speed capacity that can be used and depends on the speed that you subscribed so it doesn't mean you'll get a sharp 100 mbps on that.

54 Mbps is the speed between your computer and your wireless router. The .8 Mbps is the speed of your connection between the router and the internet. You should call your ISP and ask what your speeds should be; there could be something wrong on their end or your modem might be malfunctioning. It's also possible that your WiFi connection itself has a weak signal. That can be corrected by moving the router and the computer closer together, or getting a signal relay and putting it between them.

It is not compatible at all wifi is a wireless connection and you are adding another device called zyxel it is like i have adsl unlimited and am adding a new connection with adsl normal of course it will go down not same speed at all wifi connection is 54 mbps normal speed where as zyxel is too slow with only 10 mbps

Wireless conection will only run as fast as your slowest device. i.e.
802.11 only supported a maximum network bandwidth of 2 Mbps.
802.11b supports bandwidth up to 11 Mbps.
802.11g supports bandwidth up to 54 Mbps.
802.11n connections should support data rates of over 100 Mbps.

So if you are running a mixed network with lets say a 802.11b wifi card on a laptop and a new laptop with 802.11n, your speed will only be that of the 802.11b card.

I hope that helps.

54mbps is what the Belkin routers wireless signal transmits at! This cannot be altered and is working correctly regardless of other wireless card speeds.

The 54 mbps refers to the stream rate from the router to the wireless reciever, the 100-110 kbps you refer to is the connection speed to the internet. These are two different things, if you were transfering files from one pc to another it would transfer at a max speed of 54 mbps. If you connect via a cable it would be 100 mbps. Your internet speed depends on your isp server your downloads will be less than 256kbps, with even less upload speed.
