Clients lose connectivity with Big file transfers.

Hi.

My problem is that when I try to share files of 8 Gb or above with 5-8 machines at the same time in different APs the transfer starts OK but at certain time the user get disconnected from the AP and the transfer couldn't finish.
After the disconnection the user reconnects again normally and this only occurs in this scenario.

I don't have any bandwidth contracts or black list policies.

 

These machines are new and the files are tools  shared from some internal servers.

Any Ideas about why these machines are getting disconnected from the wireless in these case?.

 

Thanks in advance.

If you have a device that is demanding a lot of limited bandwidth, other devices will suffer.

But there are not other devices suffering, There are only disconnections from devices that are doing the file transfer.
Other devices works normally.

Did the airtime fairness helped?

One of our costumers suffered the same problem but it was due the Wireless Adapters they used.
