I haven’t seen a blue post on the slow update/download issue… and may have a fix for the others experiencing it… as well as something for Blizz to look into regarding the issue.
(See attached response i made on another post)
The may be a permanent solution if you don’t mind using the beta bnet launcher (I had for over 6 months without issue.)
I was running the beta version of bnet and never had this issue. I had recently uninstalled bnet on my pc and reinstalled and began encountering this issue. (No, there wasn’t a limit on the download speed. I tired with both the box unchecked, then set to 150,000 kb, same results, either way)
It took me a bit to remember I was running the beta version previously, and the new install was the base version.
After updating to the beta version (an option in the bnet settings), the problem disappeared.
Note: The download on the beta will also drop, briefly after the initial pulse… but unlike the live app, it WILL recover… eventually giving me 60+mb/s, “my” blizzard norm, both times i tried it by installing/deleting Wrath whose download was also broken on the base app. (This was after the beta app had already fixed the DF download issue).
I’m unsure what the specific differences are between the apps regarding the relevant code, but tech support needs to look into it and correct the issue with the current production app.
Edit: Like many others, I have more than sufficient bandwidth, sync 500mb plan on 1g fiber and were/am not having issues with downloads from anywhere else. 540mb down and 480mb up on speed tests… other downloads only limited by server side throttling… 50mb or 150mb in most cases. FTP downloads from my cousin, who is on a sync 250mb plan, come in at 250mb.
Obviously, some reports will involve client side pc/network issues. Please just be aware that not all of them being reported at the moment fall into that category.
