Loss of speed with wireless

I have the same problem. I tested the internet download speeds wired and wirelessly and see a loss of 4 mbps with wireless hook-up. I called Motorola also and they suggested the same thing, change channel raise modem. I didn't see a marked improvement and may take the item back if I can't get the speeds closer to 10 mbps. The range also seems less than my last router from Netgear.

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.

Are you trying to connect the laptops via wireless? Is that where you are seeing 75 mbps? I am assuming you are, and 75 mbps is really not how fast your internet connection is. Rather, that is how fast you are transferring data from your laptop to the wireless router and back. Generally speaking, this should be a way faster connection than your internet is running at. Chances are your internet connection speed is 10 to 20 mbps, which is good and fast.

It is easy to get the two confused, but basically a wireless connection of 75 mbps is an uber fast connection to your wireless router, and only if your actual internet connection was faster than that 75 mbps would you see any slowness due to that.

Wireless N routers are capable of delivering up to 100 mbps connection speeds, but again that is only from your device to the router. The router then goes to your modem and out through the internet. Chances are that connection is not 100 mbps because of interference, which can be walls, other wireless devices, etc.

One way to test your actual internet connection speed is to go to www.speedtest.net and click on one of the links on the map. This will tell you how many mbps you get to the internet.

WRT160N Wireless Router : i just bought a new laptop and a lynsis wrt160n......


The wired and wireless speed will always be different.
The maximum wired speed will be 100 Mbps. That means the wired connection is working properly.
Wireless connection speed will depend on the router and the wireless adapter on your computer.
If you are using B-Adapter then max speed will be 11 MBPS. IF it is G-Adapter then max speed will be 54 Mbps.
The N-adapter will give you more speed.
Check in the Device manager which adapter you are using on your wireless computer.
One more thing you can try changing the wireless channel on the router.
You will need to access the router settings page.
Update the drivers of your wireless adapter on the computer.
You have WRT160N router.
This router has issues with the Firmware.
Is there any computer connected to the router with the cable.
If not then you will need to connect the computer to the router.
Download the firmware of the router from the manufacturer's website.
enter the model number. select proper version number and download the firmware of the router.
Once you download the firmware, you will need to open the router set up and upgrade the firmware of the router.
After upgrading the firmware, it is recommended that you reset and reconfigure the router.

I just installed d-link wbr-1310. I am getting 1/4 the speed using wireless. Are there any setting I change to resolve this.


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.

Hi. just got cable internet (Comcast) and am


that's normal, wireless is normally between 1/4 and 1/2 the speed of your wired connection. normally the router gives priority to wired devices, but this should not cause you any further slow down unless you have wired devices plugged in at the same time you are using wireless. this can be changed from your router's admin page.

What is the maximum speed


The speed of that router is 100 mbps (wired) and 54 mbps (wireless). If you have a 1 mbps line, that router is more than sufficient. Your speed will change simply because someone is using the internet connection. Downloading, uploading, surfing, chatting, listening to internet radio, etc. Make sure no one is on, then test it to see what speed you get. Go to www.speakeasy.net/speedtest and select the server nearest to you. It is a very good speed tester.
Good Luck!

Wireless routers


If your connection without the router is only 30 mbps, the speed with which you will connect will never be greater than 30 mbps. Adding the router adds latency, so yes a router will always slow your internet connection slightly. 11 mbps is still pretty fast considering when you are downloading something from a website the average speed is about 270 kbps. My wireless router connects my laptop at 54 mbps, it is a wireless N router, which is faster than a wireless G. That could be another factor.

Internet speed with wireless connection to my router is almost half as compared to when i connect to my router using a cable.


As far as i know the coonection speed on internet should be the same, the speed at which you connect to the router wirelessly would be half the speed ,hence 54 mbps as apposed to 100 mbps via cable, when downloading. I assume you have done a speed test at http://www.thinkbroadband.com/speedtest.html to give you your modem connection speed, although your wireless connection to your pc; will stream the connection at half that of cable.

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.
