This issue is most likely due to the quality of the signal between the PC and the wireless. If there is a lot of interference or the wireless devices are far from the 3COM, then the signal will be less then optimal. Sinnal quality will degrade quickly when going through walls floors and celings as the density and metal contained in these structures block wireless signals. Interference can come form other wireless devices, cordless phones, RC toys and some wireless mice and keyboards.

The other factor to consider is the type of wireless being used. Wireless like all technology get better as time goes by. As new technology comes out it is categorized and classified. For Wifi there are currently 5 separate specifications for wireless. They are:
802.11 (Specless) - approx 1997 era devices. operates at 1 to 2 Mbps
802.11 a - approx 1999. operates at 6Mbps.
802.11 b - approx 1999. operates at 11 Mbps.
802.11 g - approx 2003. operates at 54 Mbps
802.11 n - October 2009. operates at 100+ Mbps

If you have an old wireless device it will work with the 3COM but only at the speed it was designed for.

You can always check your speed by connecting directly to the 3COM with ethernet cable and going to http://www.speakeasy.net/speedtest/

There is no problem with your router.In fact most ISP provider sell MBPS but really does not mean you going to get 10MBPs.In your area you will share that MBPs with others.

I bought a 3com 3crwe554g72 and when it connect with my ADSL modem the speed will become very slow (-50%). I update to the lastest firmware but no help


3com used to be good things back in the old days. But this hardware is probably self destructing in some way (the problem is widespread, the manufacturer claims it is an old product and gives no solution). Do NOT buy network products from 3com (HP today). Correct me if I am wrong..

Connecting netgear 108 mbps super wireless adsl router


I noticed that the router i bought is a modem router and only needed an adsl line. I cannot connect the router to my broadband connection because i already have a modem from my ISP. So, i'll have to sell the router and buy a wired router without modem for me to successfully complete the installation and configuration.
Cheers!

Router stops responding with red alert light turned on


Is the actual router not responding or the internet?

(IE - can you still log into the router but the internet won't work, or will it not even connect to the router)
