How do I know the bandwidth limitations of a wireless router

jasondsantos
Hi all, great website here.
I'm wondering how I can figure out what my limitations are on a wireless router. So if I buy a wireless G @ 54mbps how much can be shared by each computer. Does each PC have the capability of reaching 54mbps or is it that 54mbps is shared amongst ALL PCs?
If anyone has any links about this, please share.
Thanks.

    Any connected device has a Maximum Speed Rating that is shared out between the different computers connected so in this case the 54 MBPS would be shared between all the computers accessing either the LAN or Internet if they are all running in WiFi mode.

    Naturally any not running with the WiFi will have no effect on the WiFi Connection but if it's not secured properly there is the possibility of anyone driving by accessing your Internet Connection at the very least and downloading material that is illegal and the Person/Company who is responsible for the WiFi Access point is responsible for that download even if there can be no trace found on any of their computers. They made that download possible so they are responsible.

    Then there is also the security problem of keeping your data secure as WiFi has a range of about 500 meters so unless you employ some method of preventing unauthorised computers to log in the speed can be reduced even further than your existing computers and also allow a gaping hole in your security.

    when the specs say 54 Mbps, that's in a perfect lab scenario where there's no interference by ANYTHING. in reality you'll experience probably between 20 and 30 Mbps at your best time.

    the fact that you said 54 Mbps rather than 11Mbps means you're using 802.11a rather than 802.11b/g, meaning there will be less interference for your Wi-Fi. 802.11a runs at the 5GHz range (clarification?) and 802.11b/g runs at 2.4GHz, which is the same as your cell phones, microwaves, etc. which means more interference.

    what HAL 9000 said is right. the bandwidth will be shared by everyone. and make sure to properly secure your access point.

    what's the true firewall throughput???

    often consumer level routers actual throughput is less than stated values. especially true with firewalls that have SPI.

    I thought that 802.11/g can run up to 54 Mbps and b is the one that only runs at 11 Mbps.

    The G version is faster under ideal circumstances but just like any wired LAN you will very rarely see those Ideal conditions, but you should see speeds up around 85% of the capacity or slightly more depending on WiFi Signal Strength and some other factors including just how much interference you are getting.

    where i asked for clarification. i don't use wireless and i'm just trying to remember myself. 802.11a AND 802.11g can both run at 54 Mbps, but you're better off using 802.11a because there's no chance of interference with other devices running at the 2.4 GHz range that 802.11 b/g runs at.

    i hate using a wikipedia link bc you can put whatever you want on there, so i included an ieee link too.

    So what happens with routers that have N and G. If I have some PCs with G cards and others with N cards, does that mean that the total bandwidth available is 350 Mbps? I know that both technologies can talk to each other, but does using both technologies on a router reduce the amount of available bandwidth.

    It you want speed you are better off going for a wired Gigabit connection as it is faster than any WiFi connection that is currently available.

    WiFi can never hope to compete with wired LAD when it comes to speed and available bandwidth.
