I've got a somewhat new for us from the tech who helped modem. The modem is a Zyxel c1100Z, ment for out 25MB line. It works, no real issues until a couple days have passed or when its decided to throw a fit.
The issue also occurred on a few older models we had when we only got 10MB DSL. The issue in as best as I can describe, is that after a while any and all NEW traffic will be blocked and receive a bad DNS error. Traffic that is still ongoing when this occurs, can continue to function normally. For example, I'm streaming a video and it has 30mins left to buffer. This video will continue to download, no issues. If I try to say, watch a new video, or go back a page which needs to be refreshed I will get a "Failed to load page, Check DNS" kinda error. I can continue to talk on VOIP apps when it occurs as long as I don't disconnect. To remedy this issue, I always have to power cycle it till the next time it happens and it will. The techs at Centry have no idea whats going on, they just keep saying to buy their new modems on a lease. (Their own tech gave us this out of an unopened box). This issue has also happened on 2 other Zyxels, PK5001z. I think it strange all three would do the same thing.
I have updated the firmware, made sure its not overheating. When the tech last came out, they had fixed an open box outside that had been grounding the line. When they fixed that, the 10MB PK5001 seemed to work for an entire week with no issue. So maybe there is still some kinda grounding going on that's causing the modem to trip itself? I have no clue. I have access to the modems GUI, so if you need information to help me then I will gladly provide it. Any and all help is appreciated as I would like to stop having to power cycle this every other day just to use the net.
