[Q] Using 3G and Wifi simultaneously

I have a Samsung i5800 and would like to use my data plan to use the Internet at home.
I tried setting my router Dlink DIR600 (ddwrt) to connect the phone but for some reason the Dlink is unable to connect to the Adroc network generated by android-wifi-tether.
So I thought to make the phone connect to the Dlink and to make the computers to route the internet through the android but the android does not allow the Wifi and 3G running at the same time.
Is this possible?
no!!!!!!!!
you cant link your router to your phone to boost the signal per say. What you can do is just a simple android tether to the devices you want to use at your home
You can't do that on your Android phone.
Thank you.

WiFi and FritzBox

Hi,
is there a fix for the wireless connection bug between the opo and a fritzbox?
The problem:
The opo is not able to connect to the wlan on the fritzbox with DHCP enabled more than one times.
It is a known problem, there are a lots thread out.
The point is, that the fritzbox is recongnize the opo on every connect as a new device.
When the option "always same ip to the device" is enabled the opo canĀ“t connect anymore.
Some people slove it with unchecking this same ip feature. So they will get a new ip adress on every connect.
I can not use this because i need to have the same ip all the time.
Rebooting the phone (or turning on/off flight mode) helps and you are able to connect once more.
I also tried to assign a manual ip to my phone (not using DHCP). But it not working stable. Sometimes it still crash.
Anyway i was woundering that there are no threads about that problem? Am i the only one?
Anyone knows how to fix this?
ive read about that problem but myself never faced it. (settings like you mentioned). i got the keep ip feature active + dhcp
Fritzboxes I've been connected to:
3390 (at home constantly)
7490
7270
latest firmware.
I have the Fritzbox 6490 and no problems... maybe you could try to reset the router?

Tethering wifi will not work after updating (ota) android 7

Hi,
I suggest that before the update worked perfectly.
After updating the wifi tethering does not work anymore.
In practice, the other device connects but does not navigate.
I noticed that with tethering connected and connected device if I disconnect the data and reconnect them, the connected device navigates but no longer surf the phone.
To be able to surf the phone I have to disable the router and disconnect and reconnect the data.
It's as if either surfing one or the other.
I have already reset my factory data.
My sim has no tethering block.
I've already tried to change APN (default - default,dun - default,supl,dun).
The same problem also in safe mode.
Can someone help me?
Thanks
Nobody? :crying:

Redmi 9C connected to wifi but no Internet

I just bought this phone and I'm trying to use it in my network. I use Ubiquiti products (16-port switches and a bunch of AP access points). I connected the phone via wifi to my network and it has no problem for a while until it just doesn't have Internet connection. It stays connected with its IP address intact but for some reason it cannot seem to reach the Internet. The workaround is to simply turn off the wifi module and turn it back on. It's randomly happening and the workaround is very annoying.
I have a couple of other mobile devices (iPads, iPhones, Android phones, Windows laptops, etc.) and I never experienced the issue with these. I tried connecting the Redmi 9C to all my wifi networks:
Guest wifi with captive portal
Main wifi with RADIUS authentication
IoT wifi with regular WPA2 personal authentication
I tried resetting the wifi settings of the phone. I tried reinstalling the latest MIUI fw/sw.
and the result is the same, every time. At this point, I can safely consider that there has to be something wrong with the phone. I'm not sure if it's because of the MIUI 12 update because I updated the phone to the latest firmware as soon as I got it out of the box. Is this a known issue with this phone? I have another Xiaomi phone (Mi Mix 3) on the same network without any issues.
Any ideas?

Can't access home network when phone is usb tethered?

My android phone is usually on wifi at home. My laptop has some wifi chip/antennae issues so I have to either connect to the network via a lan port or, alternatively, use android phone usb tethering. If I am connected via the latter, on the laptop I observe that I cannot connect to the router network - I cannot even access the router login page.
I don't know a simple term for this feature. I guess it works like a network switch. But is there any app that, when enabled would help me connect my laptop (when usb-tethered) to the wifi network?
