Lenovo IdeaPad S340 Network adapter upgrade

I purchased an 9260NGW Wireless-AC Adapter and I installed it in my Ideapad S340 but the computer will not recognize it.  What network adapters are compatible with this laptop?

Hi bigghek,

 

Welcome to the Community Forums.

 

You can check compatible WLAN cards here in the parts look up. Place your model number /machine type (ex. 81N7). Click Compatible under Configuration then Wireless LAN adapters under Commodity list.

 

On 81N7 machine type as example shows 01AX709 Wireless,CMB,LTN,NFA435A with 10 other substitutes and 01AX712 Wireless,CMB,FXN,8822BE M2 with 5 substitutes.

 

I hope this helps answer your query.

 

Regards

I tried to install 9560NGW from my other laptop before buying into same S340 with Ryzen(81NC), it was not recognized either, as 9260NGW for author this topic.

At the same time, Intel 9462NGW(same pins and keys by photo from support.lenovo.com) is declared as compatible (subtitute) for the S340-15API (81NC) series:

Intel 1x1 wlan working with Ryzen.JPG

which Intel assures is only possible in the version with CNVi, i.e. as a CRF module-campaign for logic on the Intel motherboard, which is refuted by your compatibility list with the S340 on the AMD platform.

Not only that, I found two professional reviews on notebookcheck.net of your T495 and T495s models with Intel 9260NGW 2x2 running perfectly in them, which, as Intel assures in some of its materials, is compatible only with Intel motherboards that have the necessary CNVi logic. How did you manage to get them to work in T495(s)? And why the 9462NGW, declared as compatible only with Intel chipsets, allegedly due to CNVi, is indicated by you as compatible with my S340(81NC), and the 9560NGW from my another laptop and the above 9260NGW from author this topic do not work in the S340 on the AMD chipset exactly the same as in T495(s)?

What is the reason for this strange behavior of obviously compatible pin and key adapters?
Not whitelisted in BIOS?

Thank you for a real answer to my question.  The cards probably aren't white listed as you suggested.

Hi, bigghek!

 

I found on some forums the comments of experts who write that for some Lenovo and HP series there are BIOS patches that remove the whitelist restriction. But for S340 such a patcher is not known to me. I think that if it was and it could be applied to the BIOS (or NVRAM), your 9260NGW and my 9560NGW would be well detected in your S340-14IWL on the Intel platform (which by the way from Lenovo is ugly squared, because even in CNVi mode they must be compatible with your chipset, only my S340 can still have some problems with AMD chipset) and on my verson with AMD platform. In general, Lenovo, purely for marketing reasons, does not allow customers to install good quality (and cheaper) components, so that there is no difference with more expensive laptops, where they install a more expensive stuffing. And only Lenovo and HP do this; we buy laptops from other companies we would have no problem installing 9260 and 9560, which are mere pennies in online stores ...

In the same way, Lenovo (like other manufacturers) took already 3 years as a fashion not to install normal IPS with 72% NTSC in most models, even in the expensive T(!) 15.6 series, which looks generally absurd and stupid against the background of a three times higher price for the same hardware as S340 , except for the reliability of components and housing! It is a form of shame for the entire notebook industry that people get the infamous 45% NTSC (less than 60% sRGB with bad colors) just because Lenovo and the rest decided to save literally $10-15 for the normal 72% IPS. By the way, which are easy to replace in half an hour. What idiot marketer in the R&D department decided that people in the business segment or in a series like the S340 do not need IPS panels with normal color reproduction? Why did they decide that people who buy S340 or E series or L or T series do not need to look at their own pictures from their smartphone with normal colors on screen? With that. that any smartphone for $90 has IPS cooler in colorspace than Lenovo laptops for $1200 ... this is nonsense!

Re: Lenovo IdeaPad S340 Network adapter upgrade

bigghek,

Search for LG IPS with 72% NTSC on panelook.com. LG best variants. Or AUO (but it have 50/50 chance with "FlickerFree" and problems with VCOM tests - google it). Usually, AUO IPS have better viewing angles, higher brightness, but more backlight bleeding in the corners and edges. Not buy NVxxx IPS! It's not flicker free(low PWM) in most variants. For max white and black uniformity seek for strings in backlight, not edge backlight. This is these are extremely rare options. Seek for native contrast from 1200:1+ (1500:1+ is perfect for eyes)  if there is such a choice in the panelook catalog and this variants are available in stores. Not buy IPS with 100% AdobeRGB it instead of normal colors, on the contrary, you will get poisonous(oversaturated) red faces and poisonous green grass without careful hardware calibration in the OS and programs, which is far from always possible. Not seek for 120Hz  IPS it not work in S340 - no control of brigthness. Not seek for 144Hz IPS it not installed - need more pins in video-socket. Only 60Hz variants is worked. With same frame и сonnector position, plus the exact same size between the pins in the video-socket on panel, as on yours, you also need to pay attention to this, as well as the necessary power in W for the backlight and the panels, voltage and current from motherboard.
