Slow internet for my hardwired computer

I have comcast cable for internet for my home computer, but wanted to set up a wireless network for when I use my work computer at home. After installing a wireless belkin (N) router between my modem and Mac, the wireless connection is fine for my laptop use, but now internet on the Mac is much slower.
Is this a common issue when using wireless routers, and are there any suggestions on how to fix this?

Had the same problem with my Linksys WRT150N. Turned out the router had quit working for hardwired connected PC's, after all the troubleshooting, changing settings (including MTU), upgrading firmware and spending time consulting with Linksys technical support. However, Linksys was not the one who discovered the router was no good. I reinstalled an old router (G) and connected the cables the same way it was with my Linksys and found the internet on the hardwired connected PC working excellent. Another sign the Linksys router was bad was when typing the IP address (192.168.1.1) to configure the router, there was no response...oh well. Got about 3 yrs. out of the WRT150N.

How do i connect a netgear wireless router to comcast modem

Unplug your Comcast modem from your electrical outlet. Connect the Ethernet cord from the back of your Comcast modem into the Ethernet port labeled "Internet" on your new router. Connect an available Ethernet port from the back of the new router to the Ethernet port on the back of your computer.


Plug your cable modem into an electrical outlet. Plug your new router in an electrical outlet.


Reboot your computer. Click on "Start," then "Control panel." Click "Network and sharing." Select "Set up a new home network."

Click on the option for a router or cable modem when prompted by Windows to select your hardware. Your computer will attempt to access your new router. When the brand name for your router is listed, double-click it so your computer can configure itself to the new router.


Create a new name for your home network and create a unique password to prevent unauthorized users on your network. Your computer may reset your Comcast modem and router so your new changes can take effect.

Solution on a slow Internet connections Problem  The major  causes for a slow...

Solution on a slow Internet connections Problem 
The major  causes for a slow Internet connections. A poor-performing connection can be caused by broadband router configuration issues, wireless interference, or any of several other technical issues with your home network. Follow these steps to diagnose slow Internet connections.
 1. Broadband Router Settings
As the centerpiece of a network, a broadband router can be responsible for slow Internet connections if configured improperly. For example, the MTU setting of your router will lead to performance issues if set too high or too low. Ensure your router's settings are all consistent with the manufacturer's and your Internet Service Provider (ISP) recommendations. Carefully record any changes you make to your router's configuration so that you can undo them later if necessary.
 2. Wireless Signal Interference
Wi-Fi and other types of wireless connections may perform poorly due to signal interference, which requires computers to continually resend messages to overcome signal issues. Household appliances and even your neighbors' wireless networks can interfere with your computers. To avoid slow Internet connections due to signal interference, reposition your router for better performance and change your Wi-Fi channel number.
 3. Internet Worms
An Internet worm is a malicious software program that spreads through computer networks. If any of your computers are infected by an Internet worm, they may begin spontaneously generating network traffic without your knowledge, causing your Internet connection to appear slow. Run antivirus software regularly to diagnose and remove these worms from your computers.
 4. Running Background Applications
Some software applications you install on a computer run in the background, quietly consuming network resources. Unlike worms, these are programs designed to do useful work. Peer to peer (P2P) programs in particular can heavily utilize your network and cause connections to appear slow. It's easy to forget these applications are running. Always check computers for any programs running in the background when troubleshooting a slow network.
 5. Faulty Network Equipment
When routers, modems or cables fail, they typically won't support connections. Certain technical glitches in network equipment, however, adversely affect performance even though connections are maintained. To troubleshoot potentially faulty equipment, temporarily re-arrange and re-configure your gear while experimenting with different configurations. Try bypassing the router, swapping cables and changing network adapters to isolate the slow performance to a specific component of the system.
 6. Service Provider Issues
Internet speed ultimately depends on the service provider. Your ISP may change their network's configuration, or suffer technical difficulties, that inadvertently cause your Internet connection to run slow. ISPs may also intentionally install filters or controls on the network that can lower your performance. Don't hesitate to contact your service provider if you suspect they are responsible for a slow Internet connection.

Set up difficulties

You sure can. Start w/ the Comcast modem as long as it is NOT a USB type and hooks using a CAT-5 cable (regular network cable). Hook the comcast modem to the WAN port of the wireless router. On the back of the wireless router use the normal 1-4 extra LAN ports to hook other computers or the SD208 switch to it and other computers from there.

Word of advise if using Wireless Router, be sure to read manual and set a KEY for your network to secure it from unwanted outside use.

Unable to connect to the internet using a linksys wireless adapter. Connects to the router but can't find the internet.

Isolate the issue by directly connecting the PC to the router via ethernet cable (if possible).

If you were able to get online while hardwired connected to the router, then check the IP address of the wireless network connection, check the wireless security if the network key matches.

If you cannot get online while hardwired to the router, then directly connect the computer to the modem.

If you were able to get online while directly connected to the modem, then the problem is the internet settings on the router. Check the WAN configuration, such as DHCP or PPPoE.

If you cannot get online when directly connected to the modem, then you will need to contact your Internet Service Provider.

Wireless connection

Possible you did reset the router. Its okay to connect to that linksys network name. But if you want to customize you network name.

MAKE SURE TO USE THE WIRED COMPUTER TO SETUP WIRELESS CONNECTION.
Example : The Desktop computer that is connected to directly to router.


Just follow the steps.

Connection

try to do a power cycle. turn off everything. then turn on the modem first the the router (if you're using one) then the computers.
check if the cables are properly connected, try to use another cable for hardwired computers. for wireless computers, make sure that it's connecting to the correct wireless network and you are using the correct wireless password (wpa/wep)
if you want to check your wireless settings, just log in to your router's page by typing http://192.168.0.1 on the address bar of your web browser. by default the username is admin and there's no password. you will be prompted by the router's page, go to the wireless section and check the router settings are the same with what the wireless computers are using

hope this'll help you but if you still have a problem, just give me your network setup (i.e. brand of the modem, router, number of computers and if PCs are hardwired or wireless)

cioa!

Please help...internet won't connect

You may be running into a problem of your ISP only allowing one computer on the internet. while the internet is on can you access the internet from the desktop comcast originally setup?  If so that is more then likely your problem.

I have comcast myself and they told me they do not allow home networks. I fixed that problem by using the mac address cloning feature in my router.

The setup cd is also junk, all you should really need to do is:
1. unplug modem, router, and turn off computers
2. Plug modem into router
3. Plug computers into router (don't worry about wireless right now)
4. Turn on modem, wait 20 seconds or so for lights to set,
5. Turn on router. again wait for lights to set
6. Turn on ONE computer that is hard wired into the router
7 Try to surf the net.
8. If successfull try to connect wireless computers (Without using cd) and see if they surf.

If not call comcast and see if your computers are trying to obtain real-world ip's instead of LAN ip's like they should.
If so, you'll need to enable DHCP on the router.
