How to use adsl modem

My modem ADSL data light keeps flashing and sometimes does not appear affecting my ability to acces the Internet.
I usually have to re-boot my computer and this seems to solve the problem for a time. It is very inconsistant and anoying.Thank youM. Davis

ADSL DATA light flashes says there is internet activity (Internet status: Connected)...
ADSL DATA when off says there is no internet activity (Internet status: Not Connected)...

This occurs when there is a lot of noise in your telephone line...
It is adviced to do a line test in this case to find the amount of noise in your line...
If there is a lot of noise your modem will lose the internet connectivity and will try to re-establish the connection with ISP...
In this case the ADSL DATA light switches between OFF and ON...

One more thing...
ADSL SYNC light should be steady...
If it is blinking is says there is no syncronisation between your modem and ISP...

According to the user guide, the modem is trying to connect to the isp. If it is continually blinking, check all your cables. Once you are satisfied all cables are properly connect contact the isp to find out if there is an outage in your area and if not they can help you.

reset set the modem first. then connect the one system to adsl modem. type 192.168.1.1 in browser. enter user name&password.go to interface setup tab-internet--select bridge mode--save and reboot. now remove that take router connect to system type 192.168.1.1 in browser. enter user name&password.go to interface setup or advance setup in that wan tab or internet tab select dynamic ip and lan page give different network address eg-10.0.0.1 for router 10.0.0.2-...254,255.0.0.0,10.0.0.1 save and reboot it will work or just call 08041478653 , 9740575949

Open web browser and type LAN IP address of the wireless ADSL router in the address bar, and press Enter. The default IP address of TP-Link ADSL router is 192.168.1.1.

If the Internet light is off then there is a problem with the phone line to the ADSL modem or the modem is faulty or there is a problem at the telephome exchange.
Disconnect the phone cable at the ADSL modem and connect a phone handset to this cable - check for a dial tone and that you can dial out.
If you don't get a dial tone, use a different or new phone cable.
If the phone line is OK then : -
Ring your ISP to get them to test your connection to your ADSL
modem.

Look for MAC Address Clone setting on the router's Setup Page. Just enable that and power cycle the router and modem

virgin media is dsl not adsl which is the router you had

check you have typed in the correct password and username for your isp adsl connection

all ADSL routers are very fussy when it comes to power fluctuations, even the tiniest can set them into error, first thing to try, is pull the power cord out of the back of the modem, wait a couple of minuteds, then plug it back it, give it a few moments to re-connect and see how it is, if no luck with that, check the DSL, or ADSL light is on and solid.. if so look on the bottom of the modem for an ip address, open internet explorer browser, type that ip address into the address bar and hit enter, it should prompt you for a username and password.. usually ADMIN for both user and pass.. then go to "status" or "diagnostics" depending on the modem, and it will give you a run down on any potential problem..

PPP error: username and password are wrong (Authentication Failure)

I suggest a new ADSL modem, I have seen issues before where intermittent connectivity issues are solved by replacing the ADSL modem.
