[Completed] HKC P774A with no wifi - XDA Assist

Hey, friends, I think this is a hardware problem. But I am looking for a way to restore wifi to this tablet, inexpensively.
wifi just abruptly quit. Won't turn on. Tablet stalls at "turning wifi on" but there's never any wifi now.
First I tried doing the hard reset a couple of ways. Then installing the update from HKC website for 8GB P774A via micro SD card. Still no wifi.
So, I suspect the wifi chip has failed.
I rooted the tablet and decided to play with it. Used VRoot and now have Android 4.1.1. No wifi, haha.
The tablet supports USB OTG. Can I rig something like a RTL8188xxx dongle? I have a RTL8188CU dongle that I connected with the USB OTG cable, but it isn't recognized. I am wondering if I have to set up a cable to add power as shown in YouTube Connecting a Alfa AWUS036H USB adapter to android Samsung galaxy S2 with Pcap capture . If I stick a Bluetooth dongle in there, it does get power but the tablet doesn't recognize it. It can read a card reader, too.
Or, will it have to have a new wifi controller soldered on? Since there is zero wifi, not just a low signal or a connection problem, I think we can rule out the antenna. Is that correct?
Sorry for the questions. I am chemical technician, not electronics or apps developer. This tablet is like-new because it was a Christmas gift that was used about twice. It's still under 1year warranty, technically, but we have no receipts and we can't make a warranty claim. I've USB tethered it to PC to get it onto the Internet. But, you know, a tablet with no wifi is kind of useless except to parents who want to keep their kids off the Internet.
Thanks for any advice.

Hi,
You seem to have tried a lot and had no luck, so it may very well be hardware.
But I suggest you ask for other possible suggestions here,

Good luck!

Thank you. Thread closed.

[Q] Using USB connection to console into devices on iRulu 10.1 tablet

I need help... I am new to Android tablets and operating systems so I apologize if I don't give enough information right from the start and if I am asking too simple of a question. I recently purchased an iRulu 10.1" tablet. I am very happy with it since it does what I purchased it for with one exception... I wanted to use one of the USB ports to connect my USB to 9 pin serial adapter so that I can console into different devices we use at my work. Both ports work since I am able to plug in a mouse or keyboard and both function, but the USB dongle I use on my laptop will not even be recognized on the tablet... Someone please tell me what I am missing. Is it a driver? New USB adapter? Some app? I've tried a few solutions and they have not yielded any positive results. I have installed a couple of apps and they don't even recognize the adapter as being connected. Thank you for any and all assistance!!

I wouldn't expect a usb dongle to work because I don't believe any of the Irulu devices have bluetooth capability from what I understand. I don't know for sure though since I am new to this device. I just got one (Model#: AN101 AllWinner A10 CPU) myself on Thursday and doing the research trying to flash JellyBean onto it for now.
Mine came with it's own USB keyboard/stand combo so I don't expect to need a BT keyboard but they are so nice you never can tell what I may want once I get JB on here.
I just figured I'd post to keep this thread alive for ya and input. Good luck

[Completed] [Q] Connecting Android phone to TV via an RCA Cable

So, my brother bought a new multi purpose cable for his android and asked me to connect his phone to our TV. I was a bit skeptical as to how the phone will recognise the type of output to it needs to produce in order for it to replicate the screen onto the tv
After failing at first, i tried to search in settings, however all it showed under display settings was some wireless options, which is of course not what i am looking for. My brother uses Galaxy s3 mini and sister uses Galaxy s4, connected both devices and nothing happened. i use htc m7, but my phone is only good for charging, it doesnt transfer data (probably a hardware issue, i transfer files wirelessly, so never went about repairing it)
I am attaching a picture of the cable for your reference. Any guidance in the right direction is much appreciated
Thanks!
Hi, thank you for using XDA Assist. I don't think it's going to be possible to connect your device to the tv. Although not for your device, I did find some threads that discuss this:

Wired Ethernet

Has anyone had success getting a wired Ethernet adapter working on the Note 4? I have some network testing I need to do and I need a hard-line to do it. A few articles point to this adapter by Plugable. I have already tried a trendnet USB3 NIC through an OTG adapter. The switch link-lights come on for a moment the go out quickly.
https://www.amazon.com/Plugable-Mic...0RM3KXAU/ref=cm_cr_arp_d_product_sims?ie=UTF8
It's not a Samsung or Note 4 thing, it's an Android thing. Please do some research and use the search feature, as it'll save yourself time and more importantly our time as well.
Get an OTG adapter, then search Google for the apps and info.

Don't ask me for help beyond this, as you shouldn't need it. If you feel like you need help beyond searching, you probably shouldn't be attempting it. Good luck!
OTG is not a problem but Ethernet Usb doesn't seem just related to Android OS.
Many phones are compatible with chipset AX88772, unfortunately Samsung note 4 is not.

HELP!! USB Wifi router directly connecting to an android phone.

Hello!
I have a Xiomi Note 3 (SD) Special Edition (Kate). Accidentally I dropped my device and it got broken. I have already replace the display and including to this replacement, everything is going good apart from the Wifi and Bluetooth. I assumed this to be software issue but trying so many tricks from different threads I found it to be a hardware issue at last. Anyway, now my question is as mobile data is not a cost effective solution, so to use this phone in my house using my in-house broadband wifi, can I use a USB wifi adapter/router (Xiaomi mini USB Router) to be connected via OTG cable as an alternative to my phone's non working wifi?

You can probably use a USB dongle that has WiFi and Bluetooth capability, similar to this:

You will need an OTG adapter but your device has to have the hardware and software to support OTG. I've used these on PC but not sure how it's used on android so there may be compatibility issues depending on the types of devices that the dongle supports.
If your home WiFi router has a 5Ghz network then you'll need a dongle that supports dual band, otherwise you won't be able to connect to 5Ghz, you'll have to use a 2.4Ghz network.

Nexus 5 external WiFi dongle

Hi, recently the wifi on my Nexus 5 stopped working like it should and, after lots of reboots, resets & co., I completely wiped it and flashed Nougat (Dark Rom). It gave a little hope but stopped working again soon after, so I concluded it must be hardware related. After some research I found this thread here on XDA that suggests some DIY solutions. Before opening my poor phone and cooking its motherboard as one of the methods describes, I thought that maybe it would be possible to use an external wifi dongle such as this, plugged in via an OTG cable (thought I had after successfully using my pc connected via OTG to the phone and via wifi to the router). I'm currently on Dark Rom 7.1.1, rooted with Magisk.
Does someone know if something like this is possible?
Why not open it and see if a connection is loose. Would not recommend cooking it
All the pins and cables are in place
If someone is expert enough to tell me if the dongle idea is doable it would be higly appreciated
Dark rom over here and same issue too, weird
