Comparing Wireless Quality in Laptops

I found this thread http://mangolassi.it/topic/2761/new-lenovo-laptop-won-t-allow-posting-to-mango-lassi/33 where you are talking about the problem.

Complete OS reinstall and the system is exactly the same afterwards. Something about the Lenovo-modified Windows 8.1 image is flaky and is causing very noticeable issues with posting or just basic web usage.
Might be anything. There is a lot of bloatware on there. But this feels like a network shim is in place hijacking traffic. It's just a guess but that is how it appears from the behavior.I take this to mean that you installed reinstalled the OS from the system restore partition and continued having the problem, which frankly I would fully expect.
Then some chatter about how the drivers on Lenovo's website don't work, then you mention that you are downloading a new ISO from MS directly, but you never give a status (in that thread) on the outcome of the original ISO install, instead there's a link to a post about how Lenovo is installing Superfish and
And the original suspicions were right. Lenovo put in a shim that was breaking connections so their own nefarious purposes.
Where am I missing the discussion stating that Lenovo released a driver with a shim in it?

Clean install, the moment you installed their driver the shim was there.

@scottalanmiller these drivers are still available for download after they said they fixed it??!?!

That I don't know nor do I want to attempt to find out, especially when we have very little equipment here to fall back on. We are running Windows 10 on there, which I don't believe they even support, because we couldn't get Windows 8.1 to work.

Must be missing in that thread. Dominica did a lot of testing without a lot of posting. I'm pretty sure, if memory serves, that the "broken drivers" on their site was the shim issue causing them to be broken. It's possible I'm wrong on that point. We did a lot of testing over a few days on that unit. The shim was obvious when it was there. I thought that we did a vanilla install but tried the broken drivers at one point and the shim was there. Perhaps there just weren't any drivers and we were never able to get a driver that didn't come from the restore partition.

I haven't seen anything about this anywhere else with lenovo having shims in drivers. I just googled for it now and didn't find anything. You could always download drivers vendor direct anyway.

No one was talking about the shim when we found it either. But it turned out to be there
Sometimes these things don't get talked about. Odd and rare, but it can happen.And Lenovo's PR machine to cover this up has done a great job. I can't believe how supportive of Lenovo so many people have been after the most evil vendor action I can remember happening.

To be fair Superfish was not made by Lenovo. They only thing they did was included it on their systems. It's not like Lenovo was trying to do anything malicious. They didn't do their due diligence to check software on their computers though.

Lots of people do malicious stuff using software that they acquire from others. There is no way we can make the leap to suggesting that Lenovo didn't mean to do something malicious. Maybe they did, maybe they didn't. They were willing to be risky with their customers to make a quick buck. They were willing to cripple the systems. They hid it for months. That they were being malicious I think goes without saying. If they were trying to be as malicious as this might suggest, maybe, maybe not. From what I've seen of Lenovo I have no reason to give them any benefit of the doubt. Every dealing I've had with Levono they have lacked integrity and operated without scruples. That doesn't mean that they were trying to hijack data here, but it suggests that they are the kind of company that might have.

It's also important to remember that this is a Chinese vendor and their idea of ethics are fundamentally different than they are in the west. Even if Lenovo was acting acceptably by Chinese standards does not mean that we would see it the same way. This has been one of the things that people have been concerned about, with good reason, since IBM sold the division to them a decade and a half ago - that dealing with a Chinese vendor might mean problems with how the company behaves. Does that mean that their culture or their opinions of western customers were in play in this decision? No, but as it was already a concern and it was Lenovo, not HP or Dell, that had this happen is very suggestive. It supports the fears that many people have had for years about Lenovo's integrity.

This is because people simply don't understand what the problem is/was and more importantly they just don't care.

Likewise, many American manufactures have shims and backdoors added (whether the manufacturers know or not) before products go to China. I don't want to blame China for this, the US is probably worse. Both countries are the bottom of the barrel of where you would want to go for getting gear you can trust.

Blows my mind. How can so many IT people be so paranoid about unrealistic security problems and then not care when real ones happen!!

Yeah after hearing that the NSA intercepts packages and installs their own firmware on the devices before repackaging them and sending them on.. man... just makes me think FIRE SALE!

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.
Ā
Where is the antenna in the Yoga? Perhaps poor planning of it's location is also to blame.
