lenovo g505s (locked wifi card slot)


Recommended Posts

I have a lenovo g505s laptop.

 

Right now the laptop can only reach 100 through the Ethernet or wifi card.

 

Can anyone help with a wifi chip that might work in this laptop?

it does use the mini version of a wifi card.

 

I have tried a Intel Wireless-N 7260 (7260HMW AN) Intel® Dual Band Wireless-N 7260 Plus Bluetooth 4.0 that worked in an old acer laptop i had but the laptop says locked when i try it in the lenovo.

I think my best and only option is to buy a dongle but I'm coming here to ask the gods.

oerm bios locked what is accepted if its not on the allowed list.

This is how lenovo do things. I am not sure with other brands.

I had an ideapad and it not allowed to use other cards which was not on the list until bios flashed with custom firmware.

This is not a fix for installing a different card, try this on the card(s) the g505s accepts.

Uninstall AMD Quick Stream from Add or Remove Programs.

The latest version of AMD Quick Stream is located at the link below should you choose to update or reinstall it:
AMD Quick Stream Technology
https://www.amd.com/en/support/kb/faq/gpu-166

If AMD Quick Stream is not listed in Add or Remove Programs:
Open Control Panel > Network and Internet > Network and Sharing Center > Change Adapter Settings (left hand side) > click on your connection whether you are on wifi or wired > click on "change settings of this connection" > when the box pops up look for "AppEx Accelerator" (highlight it) then click on "uninstall", click ok.  Run a speed test, you should be back to normal speeds.

Hi thanks for the reply.

 

I don't have quick stream installed.

I dont see appex in add/remove

 

I dont think its a problem with software. the cards in the laptop are old.

 

Qualcomm Atheros AR8172/8176/8178 PCI-E Fast Ethernet Controller (NDIS 6.30) - should this card be running faster then 100. my connection can do 350 (virgin media) uk

Broadcom 802.11n Network Adapter - this can only run 2g

In such cases the bios needs adapting to allow the use of other devices in the card slot by adding it to the white list, the Lenovo M93 has similar issues. I did come across a thread where the writer had modded his bios to allow the use of another card maybe a Google search would enlighten you.

Older Lenovo PC and Laptops have whitelist in BIOS that prevents installing other WiFi cards other than Lenovo-certified ones (normally indicated by FRU model number), the issue also exists in HP systems as well. And worst, these BIOS are write-protected, making the only way to remove the whitelist is to use an SPI programmer. But it requires a high expertise on modding these BIOS as incorrect way flashing the BIOS can cause problems later on.

some readings and resources here:

p/s: Seems that newer Lenovo laptops have no whitelist protection on the BIOS, thus enabling users to upgrade to better WiFi card (like the Intel AX200) without the fuss.

Same problem was with my Lenovo,damn producer loked BIOS by white list.I found modified BIOS with no wl ,renewed ....and bought USB wi-fi 5Ggz  adapter.

It is the best,easiest and cheapest solution. Now with 5Ggz router i have stable speed about 95\95Mb with ping 2. My  line is 100 Mb.

The USB module is up to 600 m/s ,bought directly from China  here

For now u can find the same but with wi-fi 6 standard.
