@OP: so does wifi work better now?

No change in wifi performance. I am still using wl, since b43 disappeared (and didn't work anyway). Currently, the loaded drivers are:

wl
r8169
mii
fjes

Blacklisted drivers are:

b44
brcm80211
brcmsmac
ssb

The only one I have been able to run wifi with is wl (wifi toggles with it). Years ago, I used ndiswrapper on an old Compaq, but I think you have to have Windows available to do that (not an option here). I have no clue about how to find b43 again. I tried b44 without success. Haven't explored further since I don't know anything about Broadcom drivers.

The Windows driver is available on the web. The XP version (often the one recommended for Ndiswrapper use) can be found, for instance, here:

https://www.wireless-driver.com/broadco ... -ver56087/

Once it is downloaded, you can install it with the Windows Wireless Drivers or the MX Broadcom Manager apps. Not sure if you need to blacklist the wl driver.

BTW: if you do use the Windows Wireless Drivers, I would appreciate your feedback about it. This is the first time we have included it by default, and it tested well during development.

Jerry3904,

Wow. That website is a minefield! I finally got it to download a file named sp72879.exe. I have no idea if it is a driver. The broadcom manager doesn't think so (it won't even show up in the search window). Actually, the provided link goes to a bluetooth driver, but I found my make and model for wifi on the site. It had only a Win 7 and higher driver advertised. I went through the process a number of times and always ended up with this file that the Manager doesn't like.

I guess I don't know what "Windows Wireless Drivers" is. It is not on the Applications list, nor in Synaptic. Since wl runs the wifi card successfully, I'm not sure why an elusive driver would increase its sensitivity, unless the antenna is not being selected correctly. I'm beginning to think I need to find an external USB dongle that Linux can support. Not an elegant solution, but I suspect the HP receiver is just junk. Since I didn't buy Windows, I can't validate my suspician. People with Apple laptops and Android tablets are just churning away on the wifi link that my PC can barely find and won't sustain.

If you have other suggestions, I am happy to try them and would love to provide feedback on whatever Windows Wireless Drivers is.

Meanwhile, many thanks for your suggestions. I would give you a thumbs up, but I never can find the "thank you" icon on this web page.

Yeah, it is terrible. Let me look around a bit more later, I'm about to have a conference call as an expert witness...

In the meantime, you might be interested in reading through the Wiki entry on Ndiswrapper:

There are some suggestions on the Interwebs that the router settings or even just the model of router or it's firmware itself can be to blame. Can you take the laptop to a public library or a coffee shop and see if the same problems occur?

One suggestion was that Linux drivers do poorly if the router is set to mixed mode (WPA/WPA2 mixed mode ) and recommended pure WPA2-PSK with AES (CCMP). Another suggestion was to change the channel on the router to 1 or 11.

None of these worked for the OP, but the problems instantly disappeared when the office got a new router.

Stevo,

Interesting about the routers. I don't really have any control over the routers in the building where I have the problem while others don't. My wifi works, it just doesn't see much signal and performs poorly while others claim they have plenty of signal. I should have followed my instincts to stay clear of HP when looking for a new laptop!

Long-shot, and possibly something you won't want to do, but is it worth researching whether you could fit a different wifi card? The manual for this machine shows that it also came with a Realtek card; it looks a really easy swap if you could find one.

Otherwise can you return it as not fit for purpose, taking some printed evidence with you?

chrispop99,

That would probably be drastic. I am on a long-term assignment in Lithuania, where I bought this dog of a PC. I am thinking I might try a USB dongle if I can find one that doesn't use a broadcom chip. That might be my best bet at this point. Thanks for the idea, though.
