Hi,

So my M7000 was working really well since yesterday or the day before when i made the update of the firmware. Since then i cannot have a connexion over 7kB/s (download and upload) And this is only during the best moment. 

I tried everything. Reboot, reset, reset to factory. But it keeps the same firmware and doesnt change a bit! 

There is no ISP file for this model on the website so i have no way to change it (if this is the problem).

I tried to downgrade it but it is not possible as it blocks around 50% and say that the file is damaged (i downloaded it 5 times on different computers with the same result so probably not the problem of the file) and i tried to reinstall the same version just in case, but with the same result.

What do i do? 

I saw that this company has quite a lot of similar problem and i'm very worry because i'm using it for my work and i need an urgent solution!

Please i really need a quick answer.

Thank you
