Weird problem. I have a MacBook Pro (Intel Core Duo, OS X 10.6.7) connected to Comcast internet service via a Motorola SBG901 wireless modem/router combo. Via ethernet, this modem/router is fast with download speeds at 15Mbs. If I disconnect the ethernet and use wireless, the speed drops consistently down to 0.5 Mbs (yes, one-half Mbs). Deadly slow. If I access the wireless network with my HP laptop, I get a high speed connection. I've messed endlessly with different settings in the HTML application for the modem/router, but nothing works. It seems like it must be a compatibility issue between the MacBook and the router, but I can't figure it out. Ideas???
Problem solved. The modem/router is designed to automatically select the best channel and defaults to "auto" during installation. In my case it was doing just the opposite and choosing the worst. Enter the HTML utility and experiment with the other channels. Reminder that you have to be connected by ethernet to access the utility, then switch to Airport wireless to run the speed test, then back to the ethernet connection to change the channel.Problem solved.

This sounds like network issue ISP...call them they will trouble shoot for you..ping your modem ..is this wifi or lan that's dropping speed ? Take a Ethernet plug one end into modem and the other end into your computer , if it stays on it's not your modem . When you test modem make sure router is not attached, This will tell you its your router is dropping wifi..now if this does not work on the modem it's the modem or ISP...if you have combo modem with router still plug Ethernet to test connection...I can go more into detail just don't want to confuse you...I hope this help...
Please check the internet settings of the Lan connection in the Mac Book. May be there is IP Address or DNS settings is installed in your Mac Book which are stopping the wireless network services. Please check the IPV4 settings in the Lan or wireless connection properties.
The cable-modem just converts from the cable-company's signals to/from Ethernet signals.
You use an Ethernet cable to connect the output from the cable-modem to the 'WAN' (or 'Internet') port on a router with wireless capabilities. Then, you configure the router to create your own wireless network, with:
* an SSID ("network name")
* encryption level (use: WPA)
* a password for your network
Then, your wireless device can cite the SSID/password to authenticate to the router.
If you have no wireless devices to connect to the internet, you don't need a new router. There is speed test software you can google and download. It will tell you exactly how fast your connection speed is. You may need to upgrade your service too. One thing to do first is to clean up your PC. That means clearing all cache, deleting useless files and cleaning the registry. A program called CCleaner will do the job nicely. Next is to max out the amount of memory your motherboard will support. Make sure you keep at least 100 Mb of free space on your hard drive.If it's any less, your PC will be really slow. Adding an additional hard drive or an external drive is the answer to that.
Telephone your Internet Service Provider.
Make them "EARN" this month's service-fees that you are paying them.
If they cannot support their modem and cannot support you as a paying customer, it's time to switch to an ISP that _does_ support you.
Number three is the reset button, then it will be default, which is all listed below.
Manual Configuration: Step 1: Directly connect your computer to the Motorola SBG901 cable modem via an Ethernet cable. This is needed as enabling security will disconnect the wireless connection until wireless on the computer is properly configured. Step 2: Open up your web browser (Example: Internet Explorer) and enter the following URL:
* http://192.168.0.1
Step 3: This will bring you to the cable modem login screen. Enter the following information:
