Everything was working fine until I upgraded my Ubuntu version to 16.04 recently.My wifi gets disconnected after every 10-20 mins. Sometimes it gets even worse and it gets disconnected in just 5 mins.
I have read this another question in AskUbuntu and tried to implement what the OP accepted as the answer.
Now what I have done till now is I got my wifi details using
sudo lshw -C network
And here is what I got
*-network description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlo1 version: 01 serial: 78:e4:00:6f:e0:e6 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=4.13.0-45-generic firmware=N/A ip=192.168.0.3 latency=0 link=yes multicast=yes wireless=IEEE 802.11 resources: irq:16 memory:c3400000-c340ffff *-network description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: enp3s0 version: 03 serial: c8:0a:a9:d2:bf:d3 size: 10Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half firmware=rtl_nic/rtl8168d-2.fw latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:24 ioport:2000(size=256) memory:c1404000-c1404fff memory:c1400000-c1403fff memory:c2400000-c240ffff
The output for
enp3s0 no wireless extensions.
lo no wireless extensions.

I also tried installing WICD and using it after removing all the configuration files of Network-Manager but it also loses connection after 20-30 mins and then gets worse by disconnecting randomly. Any solutions?
