[General] need Suggestion
Sir, I want to know what would be the best mode for me?
My modem is capable of selecting any of the modes from G.DMT to ADSL2+. I don't have any issues with the maximum speed, as I am on a 1 Mb connection so my maximum bandwidth is set by the ISP. I want the mode that would reduce line drops as my connection drops alot and the SNR remains around 16 dB (downstream).
My house is around 1 Km from the exchange. Any help would be appreciated.
Changing line modes won't really help your situation. The problem is noise in the line.
If you also have phone service (wet loop), check any filters first. If it happens often, try keeping an eye open if something you're doing coincides with the disconnect, ie., interference from another device (treadmill, AM radio, halogen lights, speakers, PSUs, etc..), or if it's windy or raining (usually it's only affected in aerial plants). Also check your modem logs if there is a pattern.
You must rule out your inside wiring first before calling your ISP to send a tech out, or else you can be charged. Hooking the modem up directly at the NID or demarcation point can also help you determine whether it's their network that's the problem, in which case you won't be charged anything.
