3com 3CRWER200-75 wireless router won´t connect to certain sites

Hi,
I have recently set up a wireless network with a 3com 3CRWER200-75. The connection is generally slow, and it won´t connect, at all, to certain websites like for example www.amazon.com or www.imdb.com.
The router is new and the software is updated. My broadband connection is powerful. My neighbour has the same ISP, same connection speed, and the same kind of wireless network but with another kind of router. His connection works very well, so i believe my problems come from the router´s settings.
I would be grateful for your help.

Configuring a 3COM 3CRWDR200A-75 router as a repeater


SETTING A ROUTER AS A REPEATER 1. Connect your computer to the repeater router's RJ45 port with a LAN cable. 2. Open a browser, then enter the router's URL configuration's IP address, This is usually something similar to 192.168.0.1 3. Enter the configuration user name and password. The router will display the various router settings. 4. Go to the page that changes the IP address of the router. Changed the IP address so that it is not the same as the main router on the network, or any other network devices. If the main router on the network is set to 192.168.1.1 then the repeater router should use a higher number (ie. 10), such as 192.168.1.10 or higher, depending on how many devices are on your network. 5. Disable the repeater router's DHCP server. This setting should be on the same page as the IP address, (this may be different depending on the make of the router). When the main router is operating normally, this server assigns an IP address to every device that is connected to your network. Because this router is used as a repeater, the main router on your network will still issue the IP addresses. 6. Also turn off the DNS server, if it is activated. This function will be taken over by the main router. 7. Disable any firewall settings on the repeater router. This is usually in the "Security" section, depending on the make and model of your router. 8. Remove all in the "Port Forwarding" section. Some routers may refer to this as "Applications and Gaming," and it allows less-restricted access to the internet. 9. Set the operating mode switch to "Gateway" or "Switch" if applicable. Also, if the repeater router is a wireless router then disable the wireless access or set it to access point only. 10. Save the settings for each page, and reboot the router. When the router boots up, the changes will allow it to act as a simple repeater. 11. Now, place the repeater router in a new location and connect both routers with a Ethernet cable in each of the router's RJ45 LAN ports, and power it up both routers.

How to secure the wireless network

You want to secure the wireless network.
Is there any computer connected to the router with the Ethernet cable?

3com linkbuilder TP/8 I bought a used 3com linkbuilder TP/8 and have no manual. Is this a wireless router? at the back there is BNC port. What is it for? Thank you


I am pretty sure what you have is an ethernet hub..not a wireless router. It would be used as a distribution site for a shared network. The BNC port is a connection for coaxial cable.

Hi,
This could have a number of causes. However, you could try adjusting your MTU settings, since this can cause problems with accessing msn and similar sites. You can do this from within the router user interface.
You may well have tried this already. If not, experiment gradually with reducing the MTU setting towards 1400 - see this link for a quick tutorial (though not your router model, I know).
http://kbserver.netgear.com/kb_web_files/n100603.asp
For safety, of course, please back up the registry, or set a system restore point, before trying this out.
Other 'fixes' depend on your OS and security settings. However, since the problem does seem to be within your new router, you might find more information on the 3com knowledgebase.

A new box will come up asking you for the networe key aka password. Enter the memorable password you have just forgotten in the upper and lower boxes and press enter. Et voila! you now have an encrypted wireless network and you can only get onto it if you know the memorable password! Have fun

PPPoE connection is set up

1. Control Panel, double-click Network Connections. 2.

On the Advanced tab, click to select the Allow other network users to connect through this computer's Internet connection check box. 4.

To do this, click to select the Establish a dial-up connection whenever a computer on my network attempts to access the Internet check box. 5. If you want to allow other network users to enable or disable the shared Internet connection, click to select the Allow other network users to control or disable the shared Internet connection check box. 6. Under Internet Connection Sharing, in Home networking connection, click the LAN (Local Area Network) connection that connects the computer that is sharing its PPPoE Internet connection to the other computers on your network.
