2.2 Troubleshooting

This problem applies primarily to the first generation Actiontec routers (rev. A-D). The NAT table is significantly larger in the second generation (rev. E) Actiontec, however, it may still not be sufficient for heavy gamers or P2P users supporting many upstream connections. See the following posts:
»MI424WR-GEN2 Rev E Configuration Thread

When a PC behind your router makes a connection to a server on the internet, the router has to "remember" which connection from which PC the request came from, since you have only one external IP address, so that when the response comes back, it is routed to the same connection on the same PC. This information is kept in the "Network Address Translation" (NAT) table.

When the NAT table is full, the router can't remember any more connections and so appears to hang. The two primary culprits in filling the NAT table are torrents, and refreshing large server lists in gaming servers such as Steam.

Firmware 4.0.16.1.56.0.10.7 displayed the results in the Firewall Settings / Security Log with entries like "NAT Error : connection pool is full. No connection created". The recent 4.0.16.1.56.0.10.11.3 firmware release increased the size of the NAT table, but users are still reporting the same problem. The Security Log entries no longer display NAT pool connection errors.

Approximate NAT table sizes








RouterRev.Size
ActiontecA-D 7,500
E30,000
F30,000
G>200,000
I>100,000
WestellA 130,000
B160,000


There are several solutions to the problem:
  • If you are in one of the following states: CA, TX, or FL, you can try requesting the Westell 9000EM router. It solved the NAT table issue.
  • If you are in the former Bell Atlantic operating area, the Rev. E (or later) Actiontec may solve your NAT problem.
  • Run your own router. See this FAQ for a list of different ways you can run your own router:

If you can't login to the router, it may be one of several things:

• When I try to login, multiple dots appear as I type.
This is a security feature and is normal.

•I used to login to the router with "password1" (or similar common password). Now that doesn't work.
In August 2010 Verizon changed the password of any customer routers that had one of several common passwords due to a published hack. The user name is admin and the password was changed to the serial number of the router*. The serial number is located on the service tag on your router under the bar code. Enter it in all caps as the password field is case sensitive.

• If you still can't login to the router, you will have to do a factory reset of the router.
The reset button is a recessed button on the rear panel of the router. Press it in for about 15 seconds (until all the lights on the router go out, then flash). After the router reboots, open a browser window to »192.168.1.1 You will be prompted to change the password on the initial screen. Any customization you have done to the router will be lost.

* - Per a post here, the password now appears on the service tag sticker and no longer is the serial number.

FIOS DHCP leases are MAC bound between the router and the ONT. When swapping routers, it is imperative to release your DHCP lease, otherwise, the new router may not be able to obtain a DHCP lease.

There are several ways to release your DHCP lease:
  • Via router GUI. Verizon routers provide this function. Some, but not all, third party routers also provide this function.

  • Power off router for two hours. Verizon's standard DHCP lease interval is 2 hours. When the existing DHCP lease has expired, the new router should be able to obtain a new DHCP lease.

  • Clone the MAC address of the old router to the new router.

  • Reboot the ONT.

  • Call the FSC to break the existing lease.


To release DHCP lease on the Actiontec or Westell router:


Actiontec MI424-WRWestell 9100EM
1Click on MY NETWORK icon at the top.Click on MY NETWORK icon at the top.
2Select NETWORK CONNECTIONS from the menu on the left.Select NETWORK CONNECTIONS from the menu on the left.
3Select BROADBAND CONNECTION (coax or ethernet) depending on your connection to the ONT.Select BROADBAND CONNECTION (coax or ethernet) depending on your connection to the ONT.
4Click SETTINGSSelect CONFIGURE CONNECTION
5Click RELEASEClick RELEASE
6Click APPLYClick OK
7Disconnect the router immediately to prevent it from re-requesting a DHCP lease.Disconnect the router immediately to prevent it from re-requesting a DHCP lease.

  • I was able to replace the Verizon router with my Time Capsule using these instructions. I am very, very pleased as I had quite a few custom settings in place that would have been time consuming if not impossible to replicate on the Actiontek. Also the Actiontek is not dual-band as are the newer Time Capsules. The first time I tried this, I tried connecting the Time Capsule to the ONT a minute or so afterwards. It did not connect successfully. I then tried this again, and waited maybe a half hour. It then connected just fine when I powered it up.

If you are unable to establish a connection between the router and the ONT, or if you are unable to release a DHCP lease, rebooting the ONT may solve the problem.
    •Disconnect the AC from the Power Supply Unit (PSU).
    •Remove one lead from the battery in the Battery Backup Unit (BBU).
    •Wait one minute.
    •Reconnect the battery lead.
    •Reconnect AC to the PSU.

When the ONT is rebooted all the alarm logs are erased, so if you are having an intermittent issue, do not reboot the ONT before getting in touch with a Verzion CSR. If it is the ONT that is causing an issue, there will be no history of the ONT's activity.

Feedback received on this FAQ entry:
  • I'm afraid this doesn't work anymore for recent ONTs. I just moved back to my house and ordered FIOS again. The Verizon technician did replace the ONT. Now, I have 2 AirPort Extreme base stations. One is 5th generation, the other one is 2nd generation. I mistakenly put the 2nd generation one as the router. So, I wanted to switch them. I first disconnected the ONT for 1 minute as prescribed above. Didn't work. the 5th generation would not get an IP address from Verizon. Reconnected the 2nd generation and it got one right away. I then powered down everything again as prescribed in the above steps (removed the battery, disconnected the AC). This time, I waited well over 5 minutes. Same result.

How can I find out why Actiontec or Westell router is crashing?
When the router is rebooted, the system log has been cleared so there is no evidence of why it crashed.

In order to save the messages from the router, you need to log to a syslog server.
If you have a system running linux, then you already have one.
If you're running Windows, you can download a free one such as the Kiwi Syslog Server.

Install and start the syslog server. You will probably want the machine running the syslog server to have a static IP address.

Configure the Actiontec to write to the syslog machine.
    • Login to the Actiontec.
    • Click on the ADVANCED icon.
    • Select System Settings. The System Settings page is displayed.
    • In the Remote System Notify Level pull-down, select the level of logging you want. Info is the most detailed and includes errors and warnings.
    • An IP address fill-in appears. Enter the IP address of the machine running the syslog server.
    • Apply.

Repeat for security logging, if desired.

Each message written to the router's log file should now also be written to the syslog server.

To logon in to the router
•Open up your browser
•Enter 192.168.1.1 into the address bar.
•Press ENTER. The router's logon screen should appear

If you see a screen asking you to establish your initial user name and password, your router has been reset to factory defaults. You will need to enter a user name and password that you want to use to access the router's GUI in the future. When you've entered the user name and password you want to use, you should be taken to the router's main status page.

Otherwise, enter your user name and password. Unless you have explicitly changed the user name and/or password, the username should be ADMIN and the password should be the router's serial number located on the service tag. The serial number should be entered in upper case. Once you've entered the user name and password, you should be taken to the router's main status page.

If you are still unable to logon in to the router, see the following FAQ:
»Verizon Online FiOS FAQ »I can't login to the VZ router


Feedback received on this FAQ entry:
  • the login instructions for the REV I router are slightly different, We now have a LOGIN password that is included on the router, and it does not use the SN of the router.
