I called back to the Tier 4 advanced support Monday morning. The "advanced" support person I spoke with did NOT understand what ftp is. I had to explain it to him. He then reported that speed was OK and explained to me about the number of device limitations with their service. When I asked where that was documented for customers, he could not give me any specifics other than to check the HN legal web pages. He did say that he was seeing a large number of packet errors (which do not show up in the modem web page on my end). He decided that it would be best to send a technician out to physically check the system. That tech should come on Wednesday, 9 January. I hope that technician understands about ftp...
HughesNet technician came today. He was awesome (even though he didn't know what ftp was). He saw errors on both the modem AND the dish. He replaced both and now my ftp access is working again. (Hope I'm not speaking too soon again.) For what it is worth, this is my 4th Gen5 modem. The previous ones were each replaced for different problems.
Again, I spoke too soon about ftp working. It worked all day every time I tried after the tech left. Then worked once at night. Then 3 hours later it stopped working. Will see what happens on Wednesday. Looks like I may have to consider Viasat (formerly Exede).
Just out of curiosity, do you know which Gateway you're using? I'm just wondering if it's San Diego, which seems to be having some issues.
You can see in the "IP Gateway Association State" on this page. It will be the three letters after the J1 or J2, as in like mine, which is J2ROS051HNSIGW0104, with the ROS corresponding to Roseburg, OR. You can see the full instructions on how to determine your Gateway on Corrosive's personal site, which is here. The site can take a bit of time to load.
