Comparing Wireless Quality in Laptops
-
How do you change out the wireless card in a Lenovo anyway. I have a Lenovo T410 and when I try to put an Intel Wireless AC dual band card it in it boots up and says"unauthorized card" I can only uses the Intel B/G/N Card that came with it as they whitelist them. What kinda of business laptop locks down the wifi card.

Yeah I did hear there was some lockdown issues with the Yoga Pros as well, luckily the card I purchased didn't have that problem.
Check if there is a BIOS update for your system, then install the card again and see if it works?

It is. I'll likely try a BIOS mod, as much as I don't like them I want my dual band gigabit wifi.

Installed mod. Had to Disable the TPM (called security chip) or else it still works but beeps 12 times before booting. I think that must do a MD5 Check at everyboot. Not sure. But the AC card works now.

I have a real issue with my HP Probook's wireless. My Elitepad and phone were getting full bars where in the same physical locations my laptop had minimum strength. It's really odd...

My ASUS Transformer Prime (TF201) WiFi performance is horrendous.
Turns out it has a lot to do with where the antenna is placed. I have seen a work around for this by soldering a flexible 'tail' antenna onto the board but that would irritate the crap out of me.
Where is the antenna in the Yoga? Perhaps poor planning of it's location is also to blame. -
@nadnerB Normally they have two antennas one will wrap around each side of the screen. I think it has to do more with bad RF shielding of other components or the case itself shielding signal to much than anything.

@thecreativeone91 Very true.
Here's some destructions on wifi card replacement with some interesting things to note (like the picky BIOS).

An interesting observation that I made was that the antennas appear to run under the palm rests (near the track pad). The antennas run along the sides of the battery.
Non-upgradable RAM is a no go for me. Nice looking unit, but I don't think that I would ever buy one.The WiFi card that Chappy McWhatzhisface, in the video, mentions is this one (link in the video comments):

Sadly even the almost $2,000 macbook pro I had was the same way. I couldn't upgrade it past the 4GB of ram it came with and that was as a 2014 model.

So when the RAM gets faulty, you are left with a pretty looking paperweight...

I would hope the continue up into the screen. If not, that's likely the issue.

Here's the official picture from the manual

I think they have placed them poorly.

After upgrading to the AC card on this laptop I've had no issues with the WiFi connection.

I wonder if my laptop has any AC cards available...
