Replace the Ethernet patch cable with another one.
Can you ping the router?
Have you power cycled the router?
Do you get a connectivity light at the Ethernet jack on the PC when connected to the router?

i only have modem direct connection from telephone company DSL... and only using 1 p.c.

and 1 more thing my lan says "limited or no connectivity"

LAN means Local Area Network...the Internet is not a LAN, it is a really really large WAN, a Wide Area Network.

If you are plugging directly into the DSL modem and getting that message on the PC, I would first try power cycling the DSL modem. (Unplug the power adapter and shut down the PC. Plug in the modem and wait until the lights on the DSL modem come on for normal operation, then boot the PC.)
If power cycle does not restore the connection it is quite possible the DSL service is down, which is a problem you have to have your DSL provider (the telephone company) diagnose.
What make/model DSL modem are you connecting to, does the DSL modem have a sync light and does that sync light come on steady or is it just flashing?

but i can connect to my internet and also when i open any online game or click full screen when watching in any website and browser it instantly disconnected can anyone please give me any solutions...
You would have to explain this statement better, I don't understand.

Many DSL modems attach to the PC by using either a USB or else by an Ethernet Cable using an RJ45 Jack. Which are you using; pic of RJ45 below.

No ethernet cable attached and the PC may well say "Network Cable Unplugged". We need to be sure of what hardware you are using before we can give more meaningful help.
