View Full Version : usb adapter for wifi

09-05-2010, 03:28 PM
I have a Philips LCD-TV 40PFL7605H. I want to use Net Tv wireless.
Is it only possible to use net tv wireless with the Philips PTA01 USB-adapter or can i use other wireless usb-adapters?
Which other wireless usb-adapters are compatible?

Only PTA01 will work, that is the one you need. See PTA01 (http://www.philips.nl/c/tv-standaar-en-tv-beugel/pta01_00/prd/nl/)

Well, if it works... I will return my PTA01 tomorrow: even with the extension cable the wireless transmission is cumbersome. Reception is only mediocre and link speed often drops from 60 Mbps to 19 or just 5 Mbps - so watching "Uitzending Gemist" or other streaming video stops each 30 seconds for about 10-20 seconds... With network cable (taken from my mediabox) NetTV streams work flawless
Note: the performance did not improve after updating to latest firmware this weekend :-(

Compared: my 2 laptops have perfect reception next to the TV and show no speed drops (60-300 Mbps, definitely not a dead wireless spot!) at all. So I have to buy a switch to 'split' my UTP cable instead.

And YES I am usually a true supporter of Philips' Sense & Simplicity. As such my 37PFL7605H is a brilliant product, only the PTA01 solution is a disappointment.

Dear Rogier1975,
I have the same TV like you and I am experiencing the same issues like you have.
I have an extra problem; When changing from NET TV to Watch TV by home-menu, the TV parameters for picture are terrible. It looks like the TV holds the resolution it got for Net TV.
The only thing that helps is using factory Installation on the home, screen menu.

Do you have the same?

I do not recognize the picture quality issue, Goingon.

My wireless issue is now "solved" by returning the PTA01 USB, and replacing it for a wired solution by buying a network switch. Now my media player, bluray and NetTV are all hard-wired :o

For the wireless performance issue, I do not know whether it is in
a. The PTA01 itself - in essence 65 Mbps should suffice for NetTV, yet why does the speed drop so often?
b. Or my 37PFL7605 - maybe its internal processing cannot cope with the PTA01 data quickly enough, making the reported and real transfer speed drop? On the other hand, would the TV not need to process equal amounts of data via the wired solution?

Still interested to know the answer, as I do appreciate the effort of making NetTV wireless for us.

Is there a simple instruction available how this works as I am thinking of buying a 7-series as well?

Don't know exactly what you want to see demonstrated but on the WiFi Mediaconnect you can find some stuff on YouTube here (http://www.youtube.com/results?search_query=Philips+WiFi+MediaConnect+&aq=f).

When I am using the PTA/01 on my 32PFL7605 directly on the TV or with the short USB extension cable I also experience speed drops from 65 Mbps to 11 Mbps, which makes watching 'uitzending gemist' impossible (pauses every 30 seconds) but when I use a 2 meter USB extension cable the connection is OK.
Although 65 Mbps seems to be sufficient for NetTV i do not understand that it is limited to 65 Mbps. I have a dual band router and devices with N capability with only 2.4GHz band have 130 Mbps and my work laptop with full N capability (2.4 and 5 Ghz bands) even does 300 Mbps.

it seems that you have a better receiving quality in 2 meters from the TV. This has nothing to do with your tv, but with your environment.

my experience with the PTA01 on a 40pfl7605:
- PTA01 direct to the USB-port of the TV results in a very bad transfer rate.
- PTA01 with the short USB-extension results also in a very bad transfer rate.

- PTA1 with a longer USB-cable (approx. 0.5m) just to get the PTA01 away form the USB-port and the backplane of the TV and NetTV via WiFi works fine for me and with a much higer transferrate than in the cases above. Just for info: My TV is placed 20cm in front of a wall and the PTA01 is still between wall and TV but much more close to the wall than near the TV - so I still can't see the PTA01.

(I suppose some EMI problems since the TV processor seems to be near the USB-port at the backplane of the TV. I'm sure Philips can ask the question if there are some main parts in the TV that run at a frequency that is in the range of or have harmonics in the range of the WiFi-transponders. It might be usefull to deliver the PTA01 with a longer USB-cable)

Same experiences on my 8605 as you have. The PTA 01 seems to have more problem than other "dongles". If i place a notebook with a "dongle" attached to the PTA, the notebook have better thoughput (150 Mbps) while the TV never have better than 85 Mbps, and the stability for PTA01 is worse. Drops occure all the time and it often looses connection.
So, what to do then?
Add an Wlan extender behind the TV.. not nice but possible.
Add a cable so that you connect directly in the TV, require some work, but will guarantee the connection.
I did the last part (via a homeplug) and it works just fine for NET TV. For DLNA it is still crappy as the FW in the TV always looses its contact with the NAS.
But, when this is solved, I have a good solution.

Something like NETGEAR WN2000RPT (http://www.netgear.com/home/products/wireless-range-extenders/wireless-range-extenders/WN2000RPT.aspx)? :cool:

I have a Dlink, but NETGEAR WN2000RPT will work just fine, according to the spec (and some other users "judgement").

I had similar issue with my USB PTA01 dongle on 8605
The signal strength was only 1-5 Mbps, while laptop was at least 72 Mbps

With the USB extended cable, attached to the other side of the TV, the strength is now 65 Mbps and NetTV operates now without any buffering.
The USD dongle is next to the Digital C+ module, so guess there might have been interferance
