Re: really see 54 Mbps with 54g?

As with any wireless protocol, 54g has overhead associated with it that limits performance. While signaling data rates of up to 54 Mbps may be achieved, like most shared media (e.g. Ethernet) throughput will be significantly less. There are two scenarios for 54g performance. In an environment with only 54g clients, throughput can exceed 24 Mbps. This performance is equivalent to that of 802.11a, although 54g is usually available over a greater range. The second scenario is where 802.11b clients are present. RTS/CTS flow control must be used to allow 802.11b clients to recognize and establish communications with 802.11g access points. This leads to delays in transmission and drops peak throughput to about 10 Mbps. 54g performance is still well in excess of the maximum measured speeds of 4-5 Mbps for 802.11b. The use of RTS/CTS is important because it provides determinism to the wireless network, ensuring a minimum bandwidth for each user. Like Ethernet, 802.11 LANs normally use a ג?œcarrier sense media accessג? mechanism to signal transmission without asking for permission from the network. As the network becomes highly loaded, collisions occur more frequently and the network can become saturated with packet retransmission attempts that eventually make it impossible for any data to get through. RTS/CTS provides a more formalized flow-control mechanism that avoids this problem.

How do i upgrade to78mb ?

Do you mean you are an Xfinity (Comcast) user?

Anyway, you might have some luck calling Comcast and asking them for a higher-bandwidth service, but really if you're connecting to your router over a wireless channel that will be your bottleneck since the 802.11g standard for wireless networking supports a maximum bandwidth of 54 Megabits per second (Mbps).

NetGear wireless router WGR614 v6 runs with speed 1 0 mbps instead of 54 mbps

how far away are you from your wireless router when your getting 10 mbps?
Please note that wireless will not guarantee speeds of 54 mbps.
It will dramatically decrease the farther away you or how much interference there is between your laptop and router.
Also check if your wireless router is set to 802.11 G mode. if you have any devices that only support 802.11B you will only get speeds up to 11mbps compared to G at 54mbps

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

wireless speed depends upon the wireless card that is installed on your computer...

if your computer have a

802.11 b/g card, it will connect at 54 mbps speed (That is the maximum speed at which the wireless can connect to the router)...

802.11 n card, it will connect at 150+ mbps speed...

Hi, Although I have N series ADSL2+ Router and a N

N series routers can communicate at a speed of 150 Mbps, only if the wireless adapter that is built-in into the computer comes under N standard...
Most of the wireless adapters comes under G standard, which can communicate only at a speed of 54 Mbps...
The N standard routers are backward compatible, which can communicate with N standard adapters at 150 Mbps, and with G standard adapters at 54 Mbps and with B standard at 11 Mbps...

The speed in which the adapters can communicate are listed below...
B - 11 Mbps
G - 54 mbps
N - 150 Mbps

Internet connection frequently drops, don't know why. Still connected to router, though not getting internet. Unplugging wireless adapter and plugging it back in fixes the problem...temporarily.


IF THE WIRELESS CONNECTION DROPS, try the following troubleshooting steps
1) connect Modem-Router-Computer
2) Open router UI (
3) User name : admin , Password: password
4) on the left hand side in the blue panel select Wireless settings (under Setup)
5) SSID: (user defined)
Channnel : 11 or 6
mode : upto 54 mbps or 150 mbps
Security : WPA-PSK (TKIP)
PASSPHRASE : (user defined)
Click apply
This should resolve the problem.

If the problem still persists u can try upgrading the drivers of the wireless USB adapter.

Problem with Pre n Router

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

Router down when copy files

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.

In my new router getting less speed in wireless connection than when connected with a cable.

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.

54g products will perform differently depending on whether or not there is 802.11b traffic in the immediate environment. The rules-of-thumb for throughput are: In an 802.11g-only environment, throughput will be between 4-5 times the throughput of an 802.11b network. The maximum throughput can exceed 24 Mbps. In an environment that includes 802.11b devices, throughput will be about double the throughput of an 802.11b network. The maximum throughput can exceed 10 Mbps. In addition, all 54g radios have better sensitivity than current 802.11b radios, and 54g provides outstanding coverage in its 802.11b compatible mode.

What is the difference between 802.11g and 54g?

54g implements the latest draft of the IEEE 802.11g specification. The two primary distinctions between 54g and 802.11g are: 1) 54g is designed to enable 54 Mbps connectivity. The 802.11g draft specification makes 54 Mbps connectivity optional, and simply requires up to 24 Mbps connectivity to comply with the specification. 2) 54g products are based on the same wireless LAN chipset, which means they are interoperable. Because the standard is not final, it is not yet possible to test for 802.11g interoperability.
