Z3 Internet Navigation Slow using WIFI on Z3

ratto — Thu, 22 Oct 2015 12:23:19 GMT

Hello all,

Recently, I updated my xperia Z3 DUAL (D6633) to a 23.4.A.1.232_R4C firmware version.

After that, I realized that internet browsing using WIFI connection is slow.

Page takes too long to load.

Tried using either Chrome and Firefox. Results are the same.

Disabling WIFI and navigating with mobile data (3G/4G) runs fine.

Made factory reset, clear cache and software repair using Phone Companion. Problem remains.

Anybody here has any ideia?

PS: tried other wifi netwoks. Tried same wifi using other devices. Problem is with Z3.

Thanks

@ratto

have you tested different routers ? download speedtest and test your wifi

also boot on safe mode and see if there are any improvements

@ratto Did you have a backup that you restored after the software repair or did you test the Wi-Fi before you restored a backup?

I found the problem.

I have a Asus RT-N66U connect as a Access Point on my Thomsom Cable Modem.

When I did the tests, I used WIFI either from Asus and Thomsom.

As the problem is Thomsom, Asus in AP mode inherited the issue....

I did a factory reset in Asus, puted it in Share IP Mode (normal router) and worked.

Now, I'll ask cable provider to change the router.

Just on thing that I did not understood. The issue just ocurred with Z3. All other devices in my home was running well.

Thank you guys for your support.

HiChristofer

I’m having same issue like Ratto. But i still not found a solution for this. Actually before one month my mobile WIFI connection was worked really well, but suddenly in one day it become slow, even i can’t access the google.com also a simple page. But connection strength is okay. I’ve tried so many ways to resolve this issue.

-Factory reset

-Reinstall android from flash tool

-Roll back marshmallows to KITKAT

-Add google DNS

But still not working. So i’m really glad if you can solve my issue.

Hi @Taurion, sorry for the late reply.

I'm sorry to hear about your device. Have you also tried a software repair using Xperia Companion? If not then I recommend that you try that as well. If this doesn't help either then I recommend that you get your device examined further by an authorised service center. You can contact your Local support team for more information on how to proceed with this.
