From your question I'm not sure what's going on. From "clicking Reconnect" I presume that is not problem with physical layer and your link between PC and router is stable. So, please do some more research with these steps:
- ping to your router = default gateway for your PC (infinitely during tests), if fails probably SW or HW problem with router (try to upgrade and then restore defaults) but check your computer too (connect some Ethernet switch and ping to another LAN host)
- ping to ISP's 1st router in the way, it could be problem with DSL link if fails
- ping your VPN remote or some another host i.e.
8.8.8.8
, if fails but 1st ISP's router is echoing, problem is on the ISP site, do traceroute to locate it - run diagnostics from ADSL router web management and maybe really consult it with the support:
- it can be problem with phone wires, missing phone splitter (if calling from same line)
- or DSLAM (distance from you), this can ISP solve by degrading your line
