I've had the official Samsung MHL adapter for a few weeks now. But just recently a problem has developed. Basically WiFi no longer works when the adapter is attached. For instance I can watch Netflix through the phone, then connect it to the TV and it'll stop. I've also tested surfing, disconnected from the TV I can surf fine. But as soon as I connect the adapter nothing loads. The WiFi symbol is still visible and connected, but it won't give me any data.
As I said this wasn't a problem until very recently. I could watch Netflix on my TV through the same phone (on three different TV's). Now on the same TV's it won't work. I haven't changed the phones firmware/OS or any settings AFAIR. Also everything being used is an official Samsung product (including the power adapter in case anyone's wondering).
EDIT: Tested mobile internet (3G) and it still works with the adapter connected. But when I tried to turn WiFi back on it won't connect until I disconnected the adapter.
EDIT2: I tried just plugging in the adapter with the plug in but without having it connected to the TV, WiFi then works normally. Its only when the HDMI cable is plugged into the TV that the problem occurs. I also went into WiFi settings on my phone and noticed it was stopping at "authentication". So I disabled security on my router temporarily and then WiFi connected with everything plugged in, but still no data, web pages still won't load. This is quite baffling.
It happened to me too. Actually, I bought two identical MHL adapters (same brand, same model...) from brando workshop. With one the condition occurred. With the other one, no wifi problem at all. At that time, I assumed it was a faulty MHL cable and didn't care. But considering that you suffered from the same symptoms, I believe that further investigation would be nice. At this moment, I have no clue on what could be causing this weird behavior. Hope more people can contribute on this...

I'm having the same issue, though with a brand new generic MHL adapter...
All my searching points to using nothing but samsung MHL adapters and power bricks being a possible solution.
Also Samsung's only suggestions are wifi dropout is normal and to use samsung adapters only...
IMO this is bull****, MHL is a STANDARD now, if I have a device that meets said standard it should function without issue.
How would you feel if you bought a samsung laptop and the USB ports only work right with samsung mice and keyboards even though they advertise standard USB ports...
Also I find it odd how I've managed to get pandora to stream music while I have my MHL cable connected some times, yet others data drops completely.
It seems more likely to drop out completely when my SGS II is decoding video+audio rather than just video.
Also, on the rare occasion where my data connection doesn't drop 100% it slows down massively, going from 2meg down to .2 meg down right after plugging in the MHL adapter.
I've tried multiple power sources too, from wallbricks, to desktop computers, to my macbook running on its battery to just an external USB battery pack. So I'm pretty sure it not a power noise issue...
Seems to me that Samsung needs to work on some software fixes...
Higher mA plugged into the MHL adapter may help. If you're only plugging it into usb (which I believe only outputs 500 mA), that could be your issue. I don't have any issues when using the AC adapter out of the box.

Are you using a original or generic mhl cable?
Nevertheless, i read some people saying that with some versions of Siyah Kernel and a 1000ma managed to resolve the issue...
I'm eager to solve this because my bluetooth keyboard with touchpad are arriving soon...

Samsung OEM.
Are you on ICS? Which one?

No. I'm still on GB. Too many little things reported as messed up on ICS as of yet for my taste.

Notice that other information reveals that it works with specific kernel, more power on adapter and GB....

Found this charger: http://www.ebay.co.uk/itm/USB-Wall-...K_iPad_Tablet_Accessories&hash=item27bfeb2ecf
Any toughts? Since it has 2.1mA, can this harm the mhl adapter? And can i charge my SGS2 with this item?
Thanks!

Don't know, I can't say. My original ac adapter works for me so I've never tried any others.
Solved

Hope it works for at least some of you
It works for me too.
I have the SGS2 with the latest 4.0.3 rom.
I think this is the solution for everybody. No need for different chargers or MHL adapters. Just find the channel that works for you.

You change the channel on your wireless router. Every router is different. Depends on what kind you have. Google how to do it for whatever model you have.

I've done, changed channel in wifi setting, and It's Solved , THanks so much
same but different...
I'm having similar sort of symptoms, but I can't quite isolate if its the same problem or not. It definitely wasn't cured by changing wifi channel unfortunately :/
Here's the deal:
I use ps3 media server on my pc to stream to devices around the house. The SG2 (i9100) is rooted, but standard rom and mostly stock. I have been using bubbleupnp as a client for ps3MS and either Vplayer or Dice Player as the video player. ALthough lately its been a bit stuttery, overall it works and plays either saved mp4 videos, downloaded music vids and stuff just fine.
I have a generic MHL adapter and a hdmi to dvi cable that I use to connect to a spare PC monitor. I plugged some spare PC speakers in the headphone socket and was prepared for viewing heaven.
The monitor mirrors the phone screen fine. I can browse the PS3MS fine and select music and it will play fine. If I play a movie off the SD card (internal or external) again its all good... clearly I don't have the wifi stopping when the mhl is connected....until... drum roll and thunder....
I select a movie to play over the bubbleupnp, then it all turns to custard...kinda, basically the phone either stops and thinks for a while, then returns to the directory tree in bubbleupnp, or just sits there on the loading screen. Dice player definately takes longer to decide its not going to do anything than vplayer, but the results the same. Every now and then I get a network error, but not all the time. Sometimes when it returns to bubble, I find that the PS3MS can't be detected either, which usually takes either a few minutes wait or a restart of the phone...
Anyway, would really appreciate any thoughts and advice. While I've found plenty of threads about mhl problems, they seem to be all or nothing. This one seemed the closest to my problem. At the moment I'm a bit unsure what part of the setup is causing the problem; it definitely seems to be something to do with how it all fits together.
I've searched for problems specific to bubble and mhl, or bubble and ps3media server and all seem ok, or at least other people have them working...
Thanks.

thank you so much.
I just got a generic MHL from Ebay and got very upset when I wasn't able to stream from my network drives from neither my Galaxy Nexus or my wifes SGSII and changing from 8 to 4 solved it.

Hello All -
Hopefully someone can help me out here. I have been trying for weeks to fix an issue I have with my Samsung Galaxy S5. Currently I have a Netgear wnr1000v2 router connected to an Arris Touchstone DOCSIS 3.0 modem (Comcast). The modem is located in my basement and my home has an Ethernet ports in every room. That being said, my modem has a Ethernet cable that ties in directly to the port to my office on the second floor of my home, no other jacks are active but the one leading from the basement to my office. The Netgear WNR100v2 is connected directly into the jack and I have another Ethernet cable going directly to my desktop. My wife has a laptop that is on the first floor of the home and there is no problem with that connection, we even can go outside. When I do speed tests on my desktop, they average about 15-25ms ping, a down speed ~90mbps and an up speed of 11-12mbps, all GB of course. My laptop has the same ping and up speed but the down runs about 40-50mbps.
This is where things get strange. I installed a the Netgear WiFi Analytics app on my S5 and I get 100% signal but it varies from 35-65mbps. I would be ok with that if it was true. Something very odd happens when I try to search the web, go on facebook, youtube or any other site or application. It just clocks and clocks and pictures never come up. I can easily switch on to 4G LTE (verizon wireless) and boom everything is there no problem. If I visit someone else's home with a wireless network, when I connect, everything is fine.
I have changed my wireless channels to 1, 3, 6, and 11, identified that I am the only network using channel 6 or 11 and although that has actually sped up my laptop connections, it has done nothing for my S5 smartphone. I only use WPA2/AES which again by taking away the TKIP with WPA2, it has sped up the laptop, but nothing for the phone. My signal strength on the phone when I am 5 feet from the router is around -35 to 40 dBm, and does not vary much until I go outside the home. I can go into 90% of the home and still get those numbers. I have unplugged the batteries in my cordless home phones, nothing. Turned off home alarm, nothing. Even other people's cell phones are slow in my home.
I do work out of the home so I have no reason not to connect to my home wifi and reserve the data for when I leave the home. One other caveat, is my work, for some strange reason requires me to have DSL for my work connection, but I put that on channel 1 and the home cable is on channel 11. They are, however, in the same room but I do not thing it would make a huge difference....I turned that off too and still no improvement.
So, I am at a loss....I have been playing with the wifi settings for weeks and I am not getting anywhere. Thanks in advance for any help, advice, or suggestions!

Kinda sounds like a dns issue. Not so much a speed/connection problem, but that would probably cause same trouble on other devices. Router should just get dns info from the modem. For laughs, see if anything is set in the router for dns. Should be blank. Same on your s5.
Hey guys,
I purchased this MHL cable on eBay and it doesn't seem to work properly on my device. Screen continuously flickers, home screen is in portrait, goes into landscape mode when I am in a app only, sound is distorted and device randomly drops the connections. Power adapter is connected and tried multiple different orders in connecting the cable & device.
Mobile does recognise the connection as the notification comes up top. Currently have the ARHD rom on the device. Found a couple posts (http://forum.xda-developers.com/showthread.php?t=1591999) on XDA and One X forum but none disclosing similar symptoms. Any ideas as to why this happens? Am I better off getting a Chromecast?
Thanks
When I connect my z2 to my TV by mhl my tablet can no longer find my WiFi, it finds plenty of others just not mine.
As soon as I unplug it from the TV it connects to my WiFi straight away.
I have tried it on 3 TV's, the same thing happens every time
Any help is much appreciated
Smart View connects then drops my Microsoft wireless adapter, my old Push 2 TV works fine. Is anyone else having this issue?
My s9+ will sometimes connect to my Microsoft wireless adapter, then other times refuse to connect after multiple attempts. Ni problem with the same setup with my s7+. I can't seem to work out how to make this repeatable. Rebooting the wireless adapter sometimes helps, trying many times again and again to connect will sometimes fix it. Once connected it stays connected however. But I repeat that my s7+ had no problems at all.
