I hope that I am up to this task today. This new router has been a real time and energy waster. See for yourself what Linksys Support wants me to do.
We may need to re-flash the firmware of your router by using the TFTP utility since there may be corrupted software on your router.
Please download the TFTP.exe file from ftp://ftp.linksys.com/pub/network. This utility will utilize the .bin file extracted from the downloaded firmware file of your router.
Before doing the upgrade, we’ll test first if we are still communicating with the router. If we are, we’ll proceed with the upgrade. Before and after the upgrade, performing reset is a must. This is to reload the factory default settings of the device. Reconfiguration will then follow according to your Internet connection type, and finally do power cycle for the new settings to take effect.
To download the firmware of your router, please indicate the exact model number and version of your router on our download site and make sure to unzip the file should it be a zipped folder that you are downloading.
To upgrade the router’s firmware using TFTP, we need to do the following:
A. Unplug the router from the modem.
B. Reset the router.
C. Wire a computer to one of the Ethernet/numbered ports of the router and check if LED’s are turned on.
D. Turn off firewall and anti-virus software on the PC.
E. Assign static IP address to the PC.
F. Force the speed of the NIC (Network Interface Card) to 10Mbps half duplex.
G. Ping the router. If we get four replies, we’ll upgrade the router’s firmware. If not, I believe it’s already a hardware failure.
H. Download the TFTP.exe file from ftp://ftp.linksys.com/pub/network.
I. Perform the upgrade without interruption by closing all other windows.
J. Reset the router.
K. Reconfigure it according to your Internet connection type.
L. Perform power cycle to refresh the devices of the new settings.
M. Set the computer’s IP address back to obtain automatically.
N. Launch an Internet browser and get online.
To reset the router, please push and hold down the reset button for 30 seconds, release the reset button, power off the router for 15 seconds and then power it back on.
Checking the lights:
1. Make sure that the power is lit. If there is no light, try a different power source and check if the power adapter is plugged securely.
2. The port that corresponds to your computer should be lit on the router’s front panel; if not, try another cable, or another port and ensure that the RJ-45 cable is connected properly.
If you do not know how to disable your anti-virus or firewall (e.g. Norton anti-virus, Norton Internet Security, Zone-Alarm, etc.), refer to the documentation of the software or call the software’s support number.
To assign static IP:
1. Click on Start, Control Panel, and open up Network Connections.
2. Right click on the Local Area Network Connection that you are using, and click on Properties.
3. Click Internet Protocol TCP/IP, and hit Properties.
4. On the General tab, click the radio button beside Use the following IP address:
IP Address: 192.168.1.5
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
5. Click OK all the way out.
If we need to force the speed of the card to 10Mbps half duplex, do the following:
1. Go to Start and click on Control Panel. Double click on Network and Internet Connections then Network Connections.
2. Right click the Local Area Connection that you are using then click Properties.
3. Click the Configure button then go to the Advanced tab.
4. Look under the Property section for Connection Type, Media Type, Connection Speed, Link Speed/Duplex Mode, or something similar.
5. Change the Value from Auto to 10 Base-T, 10 half mode, 10 no duplex, or something similar.
6. Click OK and then close.
How to ping the router:
1. Click on the Start menu, and click on Run.
2. On the box, please type cmd, and then hit OK.
3. On the black screen, type ping 192.168.1.1 and press Enter.
If we can no longer communicate with the router by pinging it, we may ask for a replacement from the store if it’s within the warranty period.
Use the following information in the TFTP utility:
Server : 192.168.1.1
Password : admin
File : browse the .bin file
To properly do the power cycle, please follow these:
1. Shut down your PC, the router, then the modem.
2. Wait for 30 seconds.
3. Turn on the modem first and wait for the lights to stop blinking.
4. Power up the router, and finally the computer.
If the problem persists even after the upgrade process, please create a Deny policy as well as the Permit only and check if the connection steadies.
