This information reflects the current status of your DSL connection.

And i think SNR values are also fine:

So this happens especially when I am downloading or watching some online streams/ being idle for some time. Then for sometime the net wont respond after some annoying crashes and restarts it becomes OK and this keeps on happening now and then. Hope u understand my frustration. I am using opendns and this is no good for me as well. So whats actually causing the problem?

1. Did you check the "idle timeout" or "on demand" setting for the router?

2. What are the SNR values when the disconnection occurs?

3. What exactly "crashes"? -- does the router hang up? or the browser crashes? is the router or the power adaptor very hot to the touch??

4. Can you see if it is a hardware problem with your LAN card?

sorry for too many questions, but this will help the experts in answering the query!

Does using WiFi pose any problems for ADSL stability? (in terms of interference or power requirements etc.)

@dnjkane
If you shift your location with the laptop, and try
surfing/ download in WIFI mode
Wireless signal strength bound to vary.

Expected good signal strength usually
within a radius of say 30 or 50 feet
conditions apply !)

will wait for further inputs here.

Still no luck bro.. Is it the problem with my line?

The problem is that net disconnects and i have to press and hold the refresh key for 1 minute or restart the browser 2-3 times and then it will come back.. Often the browser crashes during refreshing.. Tried 3 browsers and no luck..

Used both Lan & Wifi and both are the same!


Sometimes, some sites work for me, some doesn't load.. I have to refresh it a 10K times to get it loaded
