We have a verifone terminal (not sure what model but I could find out) that keeps getting the tamper error. It's happened 7 times in the last 8 months. We've switching merchants which helped for a while...

Your problem presents more questions. Has your machine been refurbished during this time? Is the location in a restaurant or bar? Does the merchant turn off the machine daily? Does the machine get dropped often? These are all things that may cause the machine to go into tamper error. Please call Frank (775)338-6634

Verifone VX 680 tampered

The tampered message usually means that the terminal is not in its original state, possibly disassembled during refurbishment. Although you'll probably not be able to clear the message permanently, you should still be able to use the terminal. Keep pressing the red cancel key until the soft pay menu appears. If that doesn't work, the terminal may need to be replaced. Also, try unplugging the terminal and then pressing the F2 and F4 keys together while reconnecting the power. This should bring you to the system mode menu. Password is 1 alpha alpha 66831. Once in the system mode menu, you should be given an option to restart the device. Not guaranteeing this will work, but it has for me in the past.

My router keep freeze with New RCA modern DWG 855T

My name is Ben and I'm your guru, i.e., mentor, an influential teacher or popular expert: a management guru. - origin from Sanskrit, 'weighty, grave', for today.

As you evaluate my advice and suggestions, there are a few things you must keep in mind:

• I did not diagnose your problem and am therefore only able to evaluate what you tell me. For example, if you ask me a fuse location, that doesn't mean that I can tell you the reason why the fuse blew.
• A thorough diagnostic approach involves the use of technical equipment, such as voltage meters. scanning equipment and other sophisticated devices.
• Lastly, fixing one problem can very easily reveal a problem with something that you might consider unrelated. If that happens, you might want to view me as being incompetent but I must rely on what you do or do not tell me.

Subject: Connecting to the Internet through a wireless router

Customer's exact description: My router keep freeze with New RCA modern DWG 855T

Discussion: I'm assuming that you are running a recent version of Microsoft Windows such as XP, Vista or 7. This will be a three (3) phase solution. It is imperative that each step be followed in order.

First Step:

Let's make certain that your operating system is ready to accept your router. Click on the following link and Microsoft will analyze your system and correct any deficiencies. Microsoft FREE Fixit Site.

Second Step:

Make certain that your router is up-to-date.

Updates are regularly posted on the manufacturer's site to fix issues you encountered while attempting to use their device. The following will guide you on how to keep your device updated and working properly.

These are the common reasons why you need to do an upgrade:

• Dropping or intermittent connection
• Fix the bugs and known issues with the current firmware or driver version
• Basic Troubleshooting did not work

NOTE: For basic troubleshooting tips in wirelessly connecting to your router, please refer to your user manual.

Firmware updates are required especially if you start experiencing connection problems within your local network. An updated firmware also fixes the bugs of its previous version as well as providing new functionalities for the device. However, this should only be done after doing some basic troubleshooting that did not work.

NOTE: Updating the router's firmware is not recommended if there are no connectivity issues.


A driver update for your adapter is necessary in order to enhance the wireless performance and functionality of your device. This is recommended especially if the adapter is not working properly after you updated the router or the computer itself. A corrupted driver will cause your adapter to stop working.

QUICK TIP: For Ethernet and wireless adapters, you need to download drivers while for devices such as routers, gateways and network access storage, you need to download the firmware. The table below will show the type of file you will download according to your device.

Third Step:

Connecting to the Internet using a Router

Choose a convenient location to begin installing your router, such as an open floor space or table. This does not need to be the permanent location of the router. For wireless routers, it may be necessary to re-position the unit after installing it as the signals may not reach all areas needed.

• Unplug the power to your Internet modem.
• Power down your computer(s).
• Plug the power in to your router.
• Connect your Internet modem to the router. The cable plugs into the router jack named "WAN" or "Internet". Turn on your Modem.
• Connect one computer to the router. Even if the router is a wireless model, connect this first computer to the router via a network cable.
• Turn on the computer.
• From the computer connected to the router, open your web browser. Enter the router's address,, and press Enter on your keyboard.
• Click Login. The router does not ship with a password, so just click Submit.

To configure the router to connect to the Internet, you must enter information provided by your Internet Service Provider (ISP) into the "Connection Type" under the "Internet WAN" heading of the router's configuration page. If using DSL Internet, you may need to enter the PPPoE username and password. Likewise, if you have been issued a static IP address by your provider, the static IP fields (including network mask and gateway) must also must be set in the router.

Since this is a wireless router, change the network name (referred to as SSID). While the router comes to you with a network name set at the factory, you may want to use something more familiar for your network. Read Changing the Router's Wireless Channel and SSID -- or some other similiar language in your user guide --for a description of this process.

Verify that this computer can connect to the Internet properly. Open a new web browser and visit a few Internet sites such as or

Finally, configure additional network security features as desired to guard your systems against Internet attackers.

That's the three step program to solve this particular problem.

If you are still having problems, follow the steps outlined in the Windows operating instructions. Unfortunately, most individuals buy computers with the software installed by the manufacturer and don't receive the full manual.

1. Open Internet Explorer
2. Click on TOOLS
5. Click on SETUP
7. Click on NEXT
9. Click on NEXT
10. Click on NEXT [this is not a typo]
12. Click on FINISH

You should now be connected.

All the best,

External Nortel Modem won't connect

DSL uses one wire pair since it runs off a POTS line (plain old telephone service).

The Nortel modems are very old - they were some of the first DSL systems that came out almost 15 years ago. They were designed to work with their own proprietary Nortel back-end (DSLAM) equipment. Since they use proprietary and now way outdated transmission protocols, they will not work with modern DSL connections since they do not support the standard DSL protocols. Unless there was somekind of firmware upgrade I wasn't aware of, its pretty much junk.

Nortel went bankrupt a couple of years ago. I used to work for them and some of the guys who designed their DSL modems worked a few cubicles away from me. I had a couple of them in the early days (we got free DSL as beta testers back in the mid-90's) - the modems are useless now, but I found the power supply worked well with my cordless drill charger.

I am using a 4100 from another (previous) service provider and the dsl light blinks red and it won't connect. Any suggestions ??

you need to check the settings since most providers has different IP addresses or different settings. you might need to reset the device in order for it to detect the settings of the new provider. I suggest you get info from the provider and read your device manual.

Power supply for 3Com U.S. Robotics fax modem.

You need 9V/1A supply (with +9V at center pin) for your model with beige case. Do not use 22V/1.5A supply for old 33.6k model with
gray case. The shapes of the cases are very similar (56k has fever
leds, no external volume control, and no connectors for external
telephone equipment and external speaker), but the power supply
voltages and currents are completely different.
I hope this will help.

Dsl sync


The question I have is,
1. Did you have sync previously and it has suddenly stopped working?
2. Is this new a new DSL activation of service to your address and has not achieved sync yet?

for 1.
The most common issue is usually a recent change within the telephone environment or equipment at your address, does any of the following fit your scenario: You recently moved your DSL equipment to another room, you have bought a new phone, answer machine, Fax machine, Sky television subscription, a monitored security alarm service has been installed at your address or health monitoring equipment has been installed or an unlikely, lightening strike or power outage has occurred around the same time as sync was lost.
Any of the previous changes may have altered the way DSL signal is being filtered or split from your standard home phone signal, all telephone line using devices except for the modem/router will need to have its own DSL filter, if security or health monitoring was installed you will need to contact your internet provider and request a line splitter installation (this can be at some cost to the user, so don't forget to check what a local electrician can do this same job for)
DSL Filters can also be very susceptible to problems after power surge/failure or lightening strike at your address. Or if you have recently moved your DSL equipment, please double check the way you have setup the filter and cables at its new location.
The only test required to verify the issue is not at your address is known as an ISOLATION TEST. The router must be checked in a Phone signal free environment, please remove all phone cables from all jack-points within your premis and plug in only your router, without a filter, you should also test your router across all the jackpoints at your address if the first phone-jack you try fails) If we got lucky, you now have sync and the problem lies with one of your phone line using devices or the filter that it is using, start plugging each device back into the phone circuit one device at a time, with a filter and check to see if the router has lost sync after each device is plugged back in until you are able to identify the problem device, filter or jack-point.

for 2.
Follow the directions exactly as above and if no problem devices, filters or jack-points are found, then ISOLATE your router again and call your ISP provider and request firstly a "port reset" for your DSL port, this should be achieved within a 24Hr period, some are able to do this within 20min of your call, if sync will still not come up it is time for the ISP or service provider to send out a technician to verify the issue is not at the port, cabinet or exchange, this may take some providers up to 5 days to achieve.

Some last thoughts,
Dont rule out the possibilty of the Phone cable used for the router has failed (test the cable on a working home phone to verify it is still working)
or you may have bought an extension cable for your router, the length of Ph cable between your router and the jack-point can be no longer than 5meters before DSL signal fade can start to occur, the router will work at its best with a 15cm-30cm Phone cable, the 1meter cable usually supplied is fine.
Also, do check the jackpoints that you are NOT using at this premis (rare occasions have found me resolving sync issues because the vaccum cleaner has taken out one of your unused jack-points under the bed, in the spare room or the neighbours visiting toddler has tried to plug in a jam sandwhich or even a small plastic toy of some sort into an unused jackpoint)
If you are able, do check that your router can get sync and connect Ok at an address where DSL signal and Sync is currently known to be working.
If you have just moved to this address and your property is over 40-50Yrs old, you may want to check with the phone line provider to see if "line insulators" have ever been installed previously to resolve line noise issues, ageing line insulators will corrupt your DSL signal especially on the high humidity days.
I realise this must seem quite broad and intensive, this testing is intended to rule out any possibility of the issue being internal to your address (as we all know TELCO technicians are all too eager to hit you with unexpected maintenance charges if the issue is found to be internal to your property, as opposed to external)

Hope this gets you closer to identifying the source of your DSL sync issues, if you are like the many DSL subscribers out there, you cant stand to be without your high speed internet for more than two minutes either.

Happy hunting.
