Stable Build 51.4.66 breaks WiFi on Windows 10

Explorer | Level 4

Since our original post was deleted (with no clear reason?), here it is again.

 

Dear Dropbox team,

 

first, let me describe the issue:

since 5 days, I'm having immense problems with my XPS15's built-in WiFi (and I'm pretty sure it's Dropbox). It started with a public, login-secured network at one of our offices, where I wouldn't get redirected to the "success" page and everthing was loading extremely slow. I then continued to use another WiFi of our company which has a normal WPA2 security, where I could easily login. But the internet was again really slow and responses came delaying. After a few minutes, WiFi shut off completely and I needed to reboot in order to see any wifi networks again (the taskbar icon still showed "connected and internet available", but in reality it didnt load anything anymore). Same process again and again (you can read below what I already tried in order to fix it).

I also tried pinging our routers standard gateway, where I had losses of packages every time. The losses were only at 25% directly after connecting to the network and then continued to rise to 100% in the following minutes, meaning the connection was dead.

Back home, I tried to use my private network, and the behaviour wasn't as bad as at the office, but still comparable frustrating. After a few minutes the connection starts to "crawl" and eventually breaks completely again, where only sometimes it would help to de- and reactive the network adapter but in most cases, only a reboot would do it. When it occured, Windows even had struggles showing WiFi networks at all.

 

It was yesterday that it even came into my mind to try and kill the dropbox processes in order to see if it has something to with that. And yes, killing the processes would then bring my WiFi back to normal! So I think we can be for sure it is Dropbox, also because the automatic background update would explain why the problem occured from one day to another, without me noticing or doing anything special. The release date of the build would also fit in here.

Continue...

 

As I first thought my network adapter was broken or Windows messed it up with an update, I already tried every possible fix I could think of:

Un- and reinstalling the network adapter, rolling back to an older driver version, rolling back Windows updates, trying another DNS setting, using the Windows network reset function (and of course the automatic network troubleshooter - haha), checked for viruses, turned off any firewalls and antivirus, resetting the IP/TCP stack, releasing the IP adress, renew the IP adress, flushing and resetting the DNS cache, resetted the hosts file, and so on. Of course I also tried reinstalling Dropbox (which is extremely frustrating with about 700.000 files....!). Also, the bandwith of Dropbox was always limited, but I think even if not, it wouldn't have such effects while syncing like, 3 files.

 

We now found to have the problem on another work machine.

 

We need immediate business support, Dropbox! This is ridiculous!

 

Best regards,

 

Thomas Reister, CEO of emodrom group

No posts are deleted by people unless they are abusive etc., however, what HAS happened is its been flagged as spam for some reason. Usually somebody would come in and unflag it within a day or so, but, as its identical to this one I'm not going to as that would just confuse things!

Unfortunately I suggest if you need immediate help you need to log a ticket on Monday or call/contact support via your Admin as you wont get it here.

You can contact support via www.dropbox.com/support
As a business user you do get priority support.

What about limiting the download and upload of the application to check that it is not consuming your Bandwidth?

We can't wait another day right now... The bug renders 2 important devices useless, maybe more?

It was always limited. Also, this shouldn't break a hotspot login, or does it?

Thanks.

The issue emodrom is that there just isnt anybody to help you - this is a user supported forum I'm afraid. Same with the support system unless you are on one of the top level Business packages (Enterprise).

I've already passed the post on to somebody in Dropbox, but, as its a weekend and they work Monday through Friday they probably wont pick it up until tomorrow day time (GMT).

I would check if you can restore back the app or install the previous Dropbox app.

One other thing you COULD try (although again I doubt it'll be picked up until tomorrow) would be reposting your issue on the specific build thread you are having issues with over at https://www.dropboxforum.com/t5/Desktop-client-builds/Stable-Build-51-4-66/m-p/279090#M4632 as the developers do monitor those threads.

I'll try that, thank you.

And sorry for my confusion, I had thought this forum would be actively monitored by employees as well.
