[REQUEST] Lenovo T520 (8AETxxWW) Whitelist Removal
(11-20-2019, 10:28 PM)olokos Wrote: It's set on Dual band by default.
I have 19 wifi networks around me as reported by AC-8260 in my PC using 2 large external antennas
T520 AC-8260 I have 3 networks, one being my Phone hotspot and another router in my room, the third one is some random wifi, still quite a difference between 19 wifis and 3 wifis Sad
Makes me a bit sad, the speeds are improved a lot, I can use my BT4.0 mouse, but there's definitely something wrong here...

Did you install the lastest Intel Driver 21.50.1 and made a reboot ?
https://downloadcenter.intel.com/product...ss-AC-8260

Also, download Intel's Clear Linux and burn it on a USB stick, no need to install as its a Live CD which has lots of Intel drivers integrated.
If under Clear Linux you also see only 3 networks, than it gets odd, try to flip the antenna cables around.

If still no luck, you may have a dodgy module. I will get 2 cards in some days, and test them in two T520's.

It seems like those networks are visible, but the reception is really bad on the laptop for some reason.
Please do report back how it goes for you.

I tried swapping grey wire with black one and there's not much difference at all, in fact I think that the reception is slightly improved, but not by much. The white wire is unused as per guide, in fact I can't plug the white wire, maybe the connector got damaged, but no idea how could it be.

Please let me know if you can connect the white wire and how it goes for you in general @Pummelchen

I am using the latest intel driver, it's reported as 20.70.13.2 date 10.09.2019 in device manager.
Can you link the latest version of this distro? I haven't really heard about it.

Hello, I am looking to see if I can get a modified bios with the WWAN whitelist removed for the Ericcson F5521GW. I cannot get the no1802 patch to work.

My current BIOS version is 1.49 8AET69WW.
The link for the original bios download is here: https://download.lenovo.com/pccbbs/mobiles/8auj30us.exe
or maybe you can pull the original bios from this file https://download.lenovo.com/pccbbs/mobiles/8auj30us.iso

@RedFoxGaming 
Here's what you need.

@Pummelchen
I noticed that after I swapped the wires 
Grey plugged to aux and black to main I am getting much better reception and most likely there's no issue at all now, kinda weird that you need to swap those, contrary to what lenovo said we should do.
I think I see much more wifi's on my PC because I use 2 big antennas there.

EDIT:
I noticed something, this particular card does in fact detect all the networks around. It's just... not always.
When I cannot see the network I need to connect to then simply turning off and on again WiFi in Windows10 helps. Sometimes it takes 1 restart, sometimes 2, once it even dropped the wifi unexpectedly and I had to turn it off and on again to reconnect. I am out of ideas what is wrong here.
Please do let me know how it goes for you Pummelchen. Maybe I would have to order a new one.

The two 8260 cards arrived today. I installed just normal, no need to switch the wifi antenna cables. One end is a bit shorter by default as one T520 was factory new. The bandwidth is about 15% faster now, I get ca. 150 MBit down and 105 MBit up. All stable with latest Intel drivers on Windows 2019.

I will upgrade the second T520 soon, but report back only if I see any issues.

What do you mean by one end is shorter?

Please do report back when you have no issues aswell twice, that will make me seriously consider ordering another card.
Thanks!

I have tried the files uploaded by killer23d, which I  thank you very much for!

Sadly it seems to crash on  windows 10 1809 64 bit. It does a bluescreen with WinFlash64.sys, I figured to update winflash from asus, but it fails.
Ended up buying a 10$ 2.5" Seagate HDD and installed windows 7 32 bit on it, I had to move wifi drivers as there was no internet and no drivers at all.
No battery drivers, so winflash would stop flashing because it won't flash without battery plugged in and charging.
Sideloaded WiFi drivers, did all the updates in windows 7 and the drivers also downloaded along.
Battery was visible and I double click flash.bat, allow UAC and it goes smoothly. I also did battery firmware upgrade while at it, as this one also crashed on Windows 10 bit, bluescreen.

TL;DR
All went great, but there's 5 beeps, pause 5 beeps and then it boots
I found out a very old post that said to switch Security Chip to Inactive and it doesn't do this anymore.

This supposedly turns off the TPM. I was wondering if there's a chance of having 1.49 bios with working TPM?

Thanks everybody, this is truly a great device Big Grin

Use this script to recompute the hashes in the .FL1 file and reflash and the beeps should be gone:

Hello!!

Well i'm by no means an expert at computers.  What i'm looking for is someone to be kind enough to give me a mini walkthrough on how to modify the BIOS on my system so that I can upgrade my wireless card.  And also ideally provide an updated BIOS i can use for my system for this.  I've just bought this used laptop and everything is great, other than the slow wireless card.

Here are the details for my machine:

Lenovo 4239CTO x64 based PC T520
Windows 10 Pro  -  Version 10.0.18363 Build 18363
BIOS Version - LENOVO 8AET49WW (1.29) 2011-07-11
SMBIOS Version 2.6

My current wireless card is:

Ethernet 802.3
1x1 11bgn wireless LAN PCI Express Half Mini Card Adapter

The new wireless card i have purchased that gives me the fated 1802 error code is:

Intel Centrino Ultimate-N 6300
Model: 633ANHMW

Any help would be greatly appreciated.  And not sure if its a stupid question, but if the fix is like a program to run vs a bunch of code to use that would be great, because i'm pretty beginner at this.

Thank you!!!
