The issue is that this hotspot is not always reliable. Some times it works for a few hours, then it will just stop working. I then reboot the computer and it will work again for a few hours, and then it will stop working again. This has been happening for months now. Even when it is working, it will sometimes drop out for a few minutes of the time. I don't know if it's related to the speed of the internet connection, or if it's related to the antennas or the dongle. I don't really have any data on this. I do know that I can sometimes connect to wifi from my computer, sometimes I can't. I also sometimes have to reboot my computer to get a connection. I really don't want to have to reboot my computer every time I want to connect to a hotspot. Sometimes it will not connect at all, or it will connect, but my browser will not load the internet. I sometimes have to use a t-mobile cable to get a connection, and if I do connect to the wifi, I can't download or stream files.
#1 - Transfer a 1.05Gb video file to and from the TC. Over wifi, transfer rates ranged from 1.3 to 1.5 Mb/s in both directions (slightly lower TC->laptop, at about 1.2Mb average). With wifi turned off using an ethernet cable and USB dongle, rates were similar. This suggests to me that the limitation at this point is the write speed, not the network. Also, it doesn't make sense that it's a network issue since the latter part of the backup completes relatively quickly even if the first part takes forever, and that's over the same network. And it seems to me that no network, no matter how slow, should be limited to 200kb in 4 hours. To me this suggests it's perhaps an issue with the SSD file space that the first ~45Mb of data is stored in...? Any way to figure out which files are being transferred as the transfer is happening?
- I've verified that the data are being written, in that if I turn the computer off and on again the TM will get the ~100 files I started with and then do the backup. It's only when wifi is off that the backup fails.
- Ideally, I'd like a new 3TB hard disk to replace the current pair. I could get up to 2TB out of that pair, but then the time between backups would be a long 6 months. This is a small inconvenience to me as it's more important that I have a backup than that I have the fastest backup, but I'd like to solve the wifi issue first.
#3 - Create a new TM backup with data from days prior to today, starting at 7:39pm. Data transfer over wifi was about 1.4 Mb/s, and was similar over ethernet cable and USB dongle. I believe that number is fairly accurate since the computer was in this room all day. This means that the network is actually quite fast over wifi, but the bottleneck is somewhere else. 827ec27edc
