I am using 2 modems to dial in pppoe to my ISP, a ISP provided zyxel VMG3925-B10A and a openreach router I purchased from europe for $20. It has become a revolving door. I will do some testing and inherently drop modem web gui access and need to power cycle the modem. I will attempt to power cycle the device and it will draw a 10.0.0.0 ip and will not get a ip4 dhcp 220.127.116.11 from the ISP. When the link drops, it will not re link, and sometimes I will then have to call customer support and ask them to re link the device as they have some type of remote link which they can alter settings in the zyxel modem.
Now not only are they getting really crappy about it now because instead of simply reauthenticating the link remotely through customer service they opt to send out a trouble ticket which means a service tech will come which takes ~2 days. I made an agreement with them that since the link drops and I have to call in, I would use their modem because it keeps their equipment in and we can be happy because they got smart and stopped relinking me remotely, they would just issue a trouble ticket and I would have to wait. Infuriating.
Now after 30 or so calls back and forth and they issued threats saying things like "I should leave it alone" and 2 customer service reps become extremely rude and attempting to strong arm me through the phone a call came from upper management came and I feel like they can handle the CS part fairly well now that they have compiled their notes and coordinated a little better.
But just as things begin to improve now the foreman and local office thinking they can bully me have now placed a vlan on it because when I attempt to connect without it my openreach will not. I felt that putting the vlans on was really dirty because now I can't use my own equipment to connect. I have a feeling it has to do with some checkboxes within the zyxel which are not available on my openreach modem.
So I called them and told them I need to test more and they start telling me no this no that we can't do back and forth. So they agree to come in and use their "tech login" so that I can login and configure it and then "they will leave and i can't get into it anymore". I also can't have their "tech login" because I will have access to everyones router. They also have chosen to not just simply change the admin password once logged into the router because thats just "a flat out no"
So they have some type of third party config that is engrained over the zyxel which may be mac linked to the device - which may also be the reason when I try to use my openreach it will not connect, perhaps the isp issues to that zyxel mac and if its not matched with the previous mac it will need to be reauthenticated by manually customer service? So it seems if I attempt to reset or hard reset they have to authenticate remotely. It also uses an ISP login so that I cannot just use the default credentials. Now I can reset and then use the default credentials but every now and again that will result in a dropped link, forcing me to call them. Same with my own equiptment, even if I leave my own modem in, I test, and I drop the link, I will have to call again.
Now unbeknowist to them I acquired the tech login and I can login to the modem any time I please, but as soon as I begin any rigorous testing its possible I lose access to the web gui and the whole process starts all over. They have yet to threaten to cancel my service but they did "suggest" I go elsewhere and there is literally 0 other ISPs in the area. We are ~5 years away from fiber it is within 100 miles being dug every 2 or so years but I don't want this to go on and I would like them to figure out their problem fast.
