HDMI stops wifi - LG Optimus 2x

I have an annoying problem: when i connect my phone to the Television with HDMI, wifi simply disconnects. Before it wasn't very important, but now i want to watch some streamings on my TV and i can't. Is there any solution? Has anyone faced the same problem?

I have the same problem but I don't know if there's a solution.

I have the same problem. Maybe we should contact the LG to fix this.

For me HDMI lost his utility without internet connection...

I got this problem too,
if you use network meter by tinyjames, realtime on screen bandwidth monitor,
you can see the actual symptons, not only Wifi disconnect
when you are downloading or Streaming like usual
if you plugged your hdmi to TV/ monitor, the speed dropped instantly getting extremely slow until no traffic is transfer (or disconnected from wifi)
if you unplug ur hdmi cable, it backs to normal
CM7 nightly build
What Rom do you guys use?
Offcial rom or other custom rom ?

I use stock V20q with SR2 kernel. The bug appeared in all previous firmwares I used.

Didn't test the speed, but no disconnects here. 3G or wifi, doesn't matter.
Django 1.2.1, 20q BB&RIL, Spica SR3R2 no OC.

Ok, I've tried this too. CM 7.2.0 RC1 - when I connect HDMI cable, low power sources at around -90dBm gets lost absolutelly. But my own wifi which is around -50dBm sometimes gets better, sometimes worse - difference is about 10dBm.
I consider this behavior quite normal, don't see a mistake about this. Theese high frequencies just act this way And this is HW related, not the problem of SW.
But try something like WiFi Analyzer, you'll see signal strenght of all available AP's on one screen. Or something like squall0833 has written to measure bandwith to get better results..

So if you are near your wifi modem the connection should work?

WMwifirouter vs Internet Connection Sharing (ICS)

I have recently started using my diamond a a modem to connect to my netbook to the net via usb. When using the standard ICS utility on the phone and having a HSDPA connection, internet pages would load really slowly and would timeout but when I installed the WMwifirouter and started using it I had no problems with the connection speed.
Anyone know why the WMwifirouter has a better connection???
Anyone know how to improve the ICS so its the same as WMwifirouter??
Thanks in advance

This is just my take.
ICS scenario:
3G network> phone > USB > PC
WMwifirouter scenario:
3G network> phone > Wifi > PC
For both protocols the three of the four are the same. The only difference is that Wifi connection to PC is a lot faster than USB connection to PC.
So, to answer your question, ICS CANNOT be FIXED, to be as fast as WMwifirouter.
Cheers
Both ICS and WMwifirouter are connected through USB so I dont understand why one is quicker than the other. Something is definetly up with my ICS program.

WMWIFIRouter doesn't use usb. It broadcasts your internet like a wireless router. Your netbook probably just had wlan turned on and automatically connected while you thought it was using the usb.

NO. Wmwifi router does not use USB. Disconnect it and you will see.
Cheers
I am using the latest version of WMwifirouter and it has 3 options on how to connect external devices: wifi, bluetooth and USB. I am using the USB option to connect my diamond to my netbook. I'm sure the wifi on my diamond is turned off when I have connected.
ICS app seems to be working fine now. Not sure if by installing the WMwifi router it changed some of the settings.
Also there is now a free app for Wifi router by HTC. See the coolsmartphone website for details.
I use my phone for connecting to internet all the time, and the problems i had with nokia e51 were the main reason i switched to touch diamond. I recommend usb connection because creating and broadcasting wifi signal drains your battery drastically and it also makes your phone generate ALOT of heat. At least thats how it was with nokia where i used joikuspot (usb and bluetooth kept disconnecting) it was pain in the ass.
so USB > WiFi for longterm use

Netflix streaming quality

I seem to be having an issue with the streaming quality of nextflix when I am at home. I have a netgear WNDR3700-100NAS router and I cannot tell the difference in quality if I am on wifi or the 3g. When I am at work on our wifi the quality is much better. At home I have several computers and a google tv and they all stream very well. Any suggestions?
Thanks,
Scott
I have a feeling the wifi router at work is industrial and is capable of more bandwidth than your home. From what you stated the quality is better at work than at home. You also stated you had a lot of internet ready devices already plugged in.
Try this, powercycle your router (it may sound trivial and you've probably already done it). I had the same issue too but I use a D-Link DGL 4500.
Also try to do a speed test from your phone and another wireless device and compare speeds. Finally make sure your router is not close to your home phone(if you have a cordless)

I will power cycle the router as mentioned. What is the best way to perform the speed test?
No landline phone at all. Also the rest of the devices connect wirelessly and were not being utilized when I have tried to use netflix on my phone.
Well stangely enough it was not a real issue at all. It seems that when the streaming first starts that the quality is a little poor. Shortly after the movie starts streaming (15-30 seconds at the most) that the picture clears right up.

[Q] HDMI stops Wifi???

Hello everyone,
another day another issue:
I connected my O2X to the TV with hdmi cable to watch a long youtube video (1hour44min) but after a few minutes the video stops and it can't load anymore.
I try to go to the browser version of youtube and my browser doesn't load...finally I go to the settings and under Wifi it says disconnected!!! I tried this several times and everytime hdmi is connected wifi seems to stop working.
Now, I'm sure LG didn't mess this phone up that much, where connecting the provided hdmi cable disconnects wifi....I mean come on surely this would be impossible? right?
Anyone had this issue before? Is the solution to get a new ROM or a new phone?
Cheers
I dont hv this problem, have you tried to reboot the machine and solve the problem?

HDMI vs. Wi-Fi Speed

Hello guys,
I'm experiencing a problem which is NOT good.
I have netflix on my LG P990 and on my PS3. Somedays ago, I've noticed that netflix was kinda lag but only on P990. So I decided to check this out.
The problem has been found: When I connect a HDMI cable to my TV and to LG P990, the wi-fi connection speed drops a LOT. I've been testing with Solid Explorer to check the transfer rate.
With NO HDMI cable connected, I got around 1.5MB/s, at the exactly moment I plug the HDMI cable, it reduces to 200KB/s or less. Sometimes it stops the transfer.
Then, when I unpplug the cable, it starts to go faster again! I've already tested 3 different ROMs: MIUI, CM7 Official and NovaHD ICS (all with FULL wipe) and the problem has been detected on all of 3 ROMs.
Is there anything I can do to solve this problem? I really like Netflix, and would like to use it on my P990 on HDMI cable.
Thank you guys!
did you try another HDMI cable?
Not yet. I will try to get another cable with my cousin to check this out. BUT, I don't think it's the cable. Thanks for you answer.
May I suggest you try this on the official LG 2.3.4 rom too? With full wipe of course.
Could be a bandwidth issues but i think its probably a poor cable.
..
How did you get netflix working with nova hd? I've never managed to get it to work on current ics roms !

Yes, I did. Tested today and got the same problem. I tested with an original SonyEricsson's Micro HDMI cable from a Xperia, and got the same.
Already tested it on another TV with HDMI and got the same.

I don't know how to get it back (and I don't think it's good ideia to go back to Stock ROM, cause this ROM is really slow )
Are there any other options?

I'm pretty sure it's not a bandwith problem. I started a file transfer without HDMI cable connected and got 1.5~1.7MB/s. From the moment I connect the HDMI, after 3 seconds, It's already in 40KB/s and then I unplugged the cable, got 1.5~1.7MB/s again.

I don't have it on Nova HD. I mentioned nova HD beacause I used it to test HDMI on Wi-FI. I use it on MIUI (GB) or CM Gingerbread ROMs
Hey guys,
after some Google search and reading a LOT of stuff, just figured out how to solve or at least get a better wi-fi speed when HDMI is connected.
I've read something about router's configuration on wireless settings could be possibly wrong.
I just logged into my router and chaged the wireless channel from 7 to 1 and eureka! Got it now. Just watched a netflix video without lag and in HD.
Seems HDMI connection when on, still causes some interference on wi-fi, but it's MUCH better now.
Tested with some file transfers as well, and got almost the same speed as without the HDMI connected. Sometimes I get the same speed on both cases.
If I have enough time on these days, I'll test with different channels.
Ps.: Channel 1 worked for me but maybe it's just on my case. Possibly you will have to check different channels on your network.
It's p990 hardware problem
if you plugged HDMI cable and connected to TV, WiFi speed drops very low almost zero
but sometime it works just fine, most of time not,
confirmed this on stock rom and CM7
using CM10 now, haven't tried yet, I think it would be the same.

Frequent MHL glitching, static output, connection drops

I've tried stock ROM, ViperOne 7.0.1, CM11 Snaptop M12+. I think it comes down to a kernel issue to an extent but I still see occasional and sporadic issues.
Stock and ViperOne perform pretty much the same (both running stock kernel) and the issue isn't as severe.
CM has just as frequent manifestation of issues yet does not automatically regain the connection either without yanking the cable.
Part of the problem might be the output device, a Pioneer SPH-DA110. It seems like it might have power problems. Sometimes when the windshield wipers are on, snow/static occurs more frequently.
I'd love it if there was a working wireless solution but I've tried everything I could think of and none work. For whatever reason, miracast only puts out black video with netflix and chromecast requires internet to work. If I screen cast using chromecast, I can't access the data myself (on the phone) as I have to make an isolated wireless network to be able to share with the chromecast.
