Drops wifi on the laptop, what to do?

Such a thing, on the laptop with the purchase buggy Wi Fi. To go over 200km to change the laptop was lazy and I just changed the adapter. But nothing has changed. I changed the driver that I just did. On windose Wi Fi, maybe for the whole day not to fall, and maybe 2 times a day. On Ubuntu at all critical, it is necessary to give the load more drops immediately. The film includes crashes every 3 minutes. Falls off as follows:
The indicator shows the signal norms as they were (only on Ubuntu, the wifi signal reduces to 2 divisions). The connection is, and without any exclamation marks. But the Internet does not. I just enable and disable Wi Fi to the Internet again appeared. This occurs when you use another router and using another provider. NID help.

Prior to this was a Ralink
Right now the Atheros AR9285

If possible, try to rent to "try" USB WiFi adapter... to ensure that the problem is still in the equipment...
As an option: disable Blutooth adapter. Well, actually to look in the event log - maybe Cho will find useful there?...
Bluetooth always werblin and network connection is also cut down. OK I'll try - Alexander.Schmeler90 commented on July 9th 19 at 13:46

Well if so, then it is better to purchase a USB "whistle" under the waffle and look to start work. the problem could be anywhere in the malnutrition PCI or instability of Sinhala to interference (sometimes even one microwave all fall off), operating channel, or location. I had a similar case, when off the signal completely in the normal location, scanned the air in SSIDer, changed the channel on the router - put 13, the channel width selected 40 MHz. And it worked. Although by law we are allowed 1 to 11 channels, but I'm only on hand, because in this range didn't broadcast. So play around with these settings, can also help.
scanned in incedere, which means channel 4+8? How to understand this? - Alexander.Schmeler90 commented on July 9th 19 at 13:48
maybe you have router dual band broadcasting or you mode dual SSID? although it is silly to expect... - Alexander.Schmeler90 commented on July 9th 19 at 13:51

Once faced a similar problem (continuously/periodically off/buggy wifi), the solution was to update BIOS.
the latest version of the BIOS is - Alexander.Schmeler90 commented on July 9th 19 at 13:50

very bad router. Try to use the router closer to the antenna than the laptop. Had a similar problem (it was a bummer new router to buy) and this method solved the problem.
