wireless - Qualcomm Atheros - Slow/Not connecting on Ubuntu, but works in Win 10 - Ask Ubuntu

i have qualcomm atheros qca6174 network driver.

i having slow wifi on linux os works fine on windows 10. when use ethernet cable works, wifi slow , doesn't connect.

can guide me on how can fix this?

here more information driver:

network controller [0280]: qualcomm atheros qca6174 802.11ac wireless network adapter [168c:003e] (rev 20)  subsystem: foxconn international, inc. qca6174 802.11ac wireless network adapter [105b:e08e]  control: i/o- mem+ busmaster+ speccycle- memwinv- vgasnoop- parerr- stepping- serr- fastb2b- disintx+  status: cap+ 66mhz- udf- fastb2b- parerr- devsel=fast >tabort- <tabort- <mabort- >serr- <perr- intx+  latency: 0, cache line size: 64 bytes interrupt: pin routed irq 35 region 0: memory @ d1400000 (64-bit, non-prefetchable) [size=2m] capabilities: <access denied> kernel driver in use: ath10k_pci kernel modules: ath10k_pci 

alright try adding line config

sudo su echo "options ath9k nohwcrypt=1" >> /etc/modprobe.d/ath9k.conf 

then reboot pc see if helped. if did not fix speed issue have trick use.

force disable 802.11n protocol. while protocol supposed provide better speed newer routers. modern day routers not use protocol can cause issues.

open terminal , use following command:

sudo rmmod iwlwif sudo modprobe iwlwifi 11n_disable=1 

now try reconnecting net if did not fix issue oh if did make change permanent issue these commands.

sudo su echo "options iwlwifi 11n_disable=1" >> /etc/modprobe.d/iwlwifi.conf 

hopefully have fixed issue , if not have 1 last thing , disable ipv6 while not sure provider has ipv6 support can cause issue routers , isp's test if issue

sudo su echo "#disable ipv6" >> /etc/sysctl.conf echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf echo "net.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf echo "net.ipv6.conf.lo.disable_ipv6 = 1" >> /etc/sysctl.conf 

for of above sudo gedit 'the filename , location' such as

sudo gedit /etc/modprobe.d/ath9k.conf 

then fine line added , remove it.

the second solution provided way test see if helps before making permanent wont need manual edits undo unless choose step makes change permanent.

if nothing provided helped please comment me etc.
