I have a linksys e2000 router and it continually drops out. The only thing I notice is that the port 3 light is on constantly. That seems to freeze it up and I cannot get it to go away. Previously, we would just power it down and reset it but that doesn't work anymore. As long as that port light is on, it simply will not work. Nothing plugged into port 3 at all. Anyone know what to do other than get a new router?

1.login to your linksys.
2.go to access and restrictions.
3.click the drop down for access policies and for each selection,check facebook has been added to the url section.
4.if found, you can either delete facebook from that policy of disable the whole policy.

Disconnect the power from the linksys for about 30 seconds then plug it back and see if it stops dropping. Most times the dropping occurs if you turn the modem and router off at night then when you turn them back on the router boots up faster than the modem and that will cause it to drop. Power outages also will cause the problem if the router boots up before the modem.

If unplugging the router and waiting 30 seconds does not solve it then unplug both the modem and the router. Then plug the modem back in and let it boot up for a minute or two, then plug the router in and let it boot up.

Error 800: Unable to establish VPN connection

This issue may be caused by a router that has outdated firmware.

Make sure that port 1723 is opened on your router.
For VPN connection , you can try opening port 500, 443-447, 10000-20000 and important port 1723 on your router.

I will suggest you to upgrade firmware on your Linksys router.
After upgrading the firmware, reset the router to factory default and reconfigure it manually.
Open the ports mentioned above and see if that works.

See How to upgrade firmware on Linksys router.

See How to setup Linksys router

you have to configure the router and give it the right ip address

you can get user manual and software of your router from given below linkhttp://homesupport.cisco.com/en-us/wireless/linksys/E2000

What are the ethernet cables on ports one and two going too? This is normal if there is any internet activity happening from this router.

If your former linksys router was NOT N but rather b/g, then the problem is likely that your new router is running N and must be reconfigured to run b/g instead of n on its wireless. The acer aspire one netbook's integrated WiFi is 802.11b/g and the only way to do 802.11n is by using a plug-in USB 802.11n wireless adapter. To manually configure the router's wireless for 802.11b/g or n...
1. Connect the netbook using an ethernet utp cat5 patch cable between one of the four RJ-45 LAN ports on the router to the 10/100 ethernet RJ-45 port on the netbook's left side.
2. Start a browser like Internet Explorer and enter IP address 192.168.1.1 (default for Linksys)
3. On the login window, enter admin for username and admin for default password, then click OK
(The password may be changed if the router's setup software on its CD has been run.)
4. On the Linksys Setup page, click the Wireless tab
5. On the Linksys Wireless page, for Network Mode, click v for drop menu and click BG-Mixed

A final note: The easiest way to setup the router is to run its setup software on the CD that comes with it. If you want to do this with the netbook (which doesn't have an internal CD drive), an external CD drive would have to be plugged into one of its USB ports.

Set up a Linksys Wireless Router

1 Choose and purchase a Linksys router, taking into account your budget and computing habits.

2 Attach the antennas to the Linksys wireless router.

3 Place the router in a central location, making sure it's not surrounded by metal. (A signal can't be obtained through metal.) The router should be located so that the distance between clients (computers) is somewhat equal. This will create a better connection.

4 Plug the Ethernet cable into the "Internet" port on the back of the Linksys router.

5 Connect a computer to the router by plugging another Ethernet cable into the Ethernet port on your computer and attaching the other end to one of the available ports on the back of the router. You can choose any port except the one labeled "WAN."

6 Plug the router into an electrical outlet.

7 Wait for the power light to stop flashing, at which time the router is finished booting up. While the router is booting, the power light will be blinking. This process may take a few minutes to complete.

8 Reboot your computer so it can access a new IP address from the router through the Dynamic Host Configuration Protocol (DHCP).

Configure the Router

1 Open your web browser, type " http://192.168.1.1/ " into the address bar and hit "Enter."

2 Use "Admin" as the username in the pop-up box and leave the password blank.

3 Connect to the Internet and click on "Internet Setup."

4 Select your connection type from the drop-down menu. Choose "DHCP" for cable modems or "PPPoE" for most DSL modems. If you are unsure of these options, check with your ISP.

5 Set a service set identifier (SSID) to identify the router and change the password.

6 Encrypt your wireless connection using a Wireless Encryption Protocol (WEP) key. Under the "Wireless Security" option, enter a passphrase and click "Generate." This will generate a password which will need to be used by any client connecting to your router.
