Re: excellent signal low speed transfer
You can boost the signal range of a WiFi computer network in several ways:
reposition your router
(or access point) to avoid obstructions and radio interference. Both
reduce the range of WiFi network equipment. Common sources of
interference in residences include brick or plaster walls, microwave
ovens, and cordless phones. Additionally, consider changing the WiFi channel number on your equipment to avoid interference.
add another access point (or router). Large residences
typically require no more than two APs, whereas businesses may employ
dozens of APs. In a home, this option requires connecting your primary
wireless router (access point) to the second one with Ethernet cable;
home wireless routers and/or APs don't normally communicate with each
add a bi-directional WiFi signal amplifier to wireless
devices as needed. A WiFi signal amplifier (sometimes called "signal
booster") attaches to a router, access point or Wi-Fi client at the
place where the antenna connects. Bi-directional antennas amplify the
wireless signal in both transmit and receive directions. These should
be used as WiFi transmissions are two-way radio communications.
add a WiFi repeater. A wireless repeater
is a stand-alone unit positioned within range of a wireless router
(access point). Repeaters (sometimes called "range expanders") serve as
a two-way relay station for WiFi signals. Clients too far away from the
original router / AP can instead associate with the WLAN through the

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.
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.
There are a few things that can cause you to lose wireless connection with your wireless router. 1. Weak signal strength, check the signal strength on your wireless card. If it is weak move the wireless router away from brick or concrete walls and if possible locate the wireless router higher up. 2. Have you secured your wireless router from people near your from unauthorized access? ie. change the default password, setup encryption use WPA2 or WPA, change the default SSID, and turn off SSID broadcast, and for added protection, enable MAC address filtering which allows only the MAC address/es of your wireless card/s to connect to your wireless router. 3. You could be getting interference from electrical sources such as air conditioners, arc welders, washing machines etc. If so, the power supply to the wireless routers and computers etc should be connected to a surge protection power board, better still connect your computer equipment to an UPS (Uninterrupted Power Supply). 4. Check the channels of the wireless routers and access points in your area and change the broadcast channel on your wireless router to an unused channel or one that is currently used but has the weakest signal strength. This will minimize interference with your wireless router from other wireless routers and access points in your area.
MBps or megabytes per second, is your data transfer rate. This varies on signal strength, quality, interferences, etc. If you can get a little closer, great if not, try to get metal obstacles out of your way to get a little better signal. Wireless ethernet is transferred via radio waves, often metal objects can obscure the signal strength. Also try moving the antenna to a horizontal position this sometimes helps.
Usually, a device will renegotiate a slower speed to compensate for interference. slower speeds are sometimes the most reliable. Its possible to change your wifi channels and try to get one that has less interference, and maintain a stronger signal. You might also want to ensure that any cordless phones in your area are NOT on the same frequency range as your router, because as soon as "Old Great Aunt Mildred" calls you or your neighbor, your wifi goes bye bye.
Wireless connections are running on a slower speed by definition.
A wired connection with this router sets the maximum speed at 100 Mbps.
A wireless signal in a 802.11b network has a maximum speed of 11 Mbps, and a 802.11g network has a maximum speed of 54 Mbps.
These numbers are theoretical numbers and never achieved in reality. (like a Toyota Prius makes 60mpg...)
So depending on your wireless network adapter and how your setup physically looks like (distance to the router, interference with telephones, microwaves etc.) it is absolutely possible that you wireless speed is considerably slower than your wired connection.
If you have any more questions, just come back here and leave a comment - I'm happy to help.
Check in your routers settings via your browser that the file transfer speed is no higher than 54 mbps, as it may be set at 108 mbps or 125 mbps as a 'g' type router should be, but your wireless network adapters can only work at 54 mbps and are crashing the transfers.
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.
