the internet connection through the adsl modem and router keeps constantly dropping
The scheme is as follows:
Transit line ------ ADSL modem ------VPN PPTP router ----- Switch----company network
--------------------- ZTE DIR-300
Sometimes it works stably - but specifically during the day - starting around 11 am a constant reconnect to the internet begins and continues until evening.
The provider says the reconnect is initiated on our side
Called the provider for a month - they say -
1. restart the equipment, - restarted the router and modem, turned it off for a long time
2. they also restart the port, -practically no changes
3. check the splitter- I say the line is used only for internet
4 . switch to another vpn server that you connect to - they gave 30 ip addresses
- switched - also practically no results
5. requested a check of the ADSL line - that probably also gave nothing,
6. connected a regular telephone - seems there's no outside noise, both during a call and at zoom
7. tried bringing up the connection with a computer - the computer at first just says
network identification, then unidentified network, then network identification again, and round and round- meaning the problem isn't with the router))
8. suddenly discovered that before me someone had made the connection to the line not through a telephone RJ-12 jack but through an ethernet RJ-45 jack - nonsense. the contacts barely made contact,
redid the jack, then re-checked the router and modem and their power supplies- it turned out the modem's PSU was not the original one - the modem says 18 AC V but the power supply says 12AC V
- found the original one- seems everything normalized)))
