Cisco DPC 3925 - WiFi on Multiple Android Mobile Devices is Extremely Slow (except Google)
For the last few days I have encountered a very strange error.
All my Android mobile device connected to my WiFi on Cisco 3925 have started lagging.
It takes about 1 minute to load any website.
My android mobile devices are : Note 7 and Xperia Table z2
What is weird only Google website is working properly.
I have searched online and found that has something to do with ipv6 and ipv4. But I really do not know how to change these setting.
My laptop is also connected to wifi and works just fine no problems.
My Iphone 6 works perfectly fine too.
I have reset my router to factory settings.
I wiped the cache of my mobile devices, changed their ip.
Please help. I would appreciate it a lot.
