I'm not a networking pro but I do have a few suggestions:
- Are you able to ping the gateway once the VM's network interface is UP?
- Is the VM configured for the correct network...

Finally figured it out after going through many many articles, guides, forums, and googling, LOL!

I was just missing the iptables configuration part. Once I created the appropriate iptable rules...

Just an update as I'm playing around more with the configurations...

I was finally able to get the test DCHP client/test system to get assigned the correct 10.0.0.x IP range!

However, no...

Hi all!

As I am still a beginner when it comes to networking I am attempting to play around and configure multiple VLANs utilizing my ubuntu isc-dhcp server that is connected to a managed TP-Link...

Just tried the code you provided, no difference thus far, no wireless networks are showing up. Ran the code once from home (yesterday) and at work (just now). The WiFi did work a couple of times,...

Oh man...that doesn't sound good, I hope not...but it does seem that way though. I never had any issues with the WiFi when the macbook pro was still using MacOSX.
The macbook pro is actually...

DId you add in "nomodeset" into the GRUB linux line? if not, give that a shot.

I'm not a pro at this but I recently installed Ubuntu 18.04 LTS onto my mid-2010 macbook pro and read up that the...

Gotcha, the BIOS should be set to default as I'm actually not sure on how to modify/update the BIOS on a Macbook.

As for the scan, nothing is showing up for now and am currently connected via...

Reproduced the issue! Just rebooted a couple of times and now the WiFI won't detect anything again...
Following is the info that I pulled:

$lsmod | grep -e wl -e b43

Hello from home!
Guess what? The moment I booted up from home, WiFi is working as it should...makes me feel like I'm going crazy haha!
Here's the information with the firmware-b43-installer:
...

Ok, purge and the install of the firmware-b43-installer was completed, will be rebooting now but have to head home now. Will post results of the change once I am home!

ok, will purge it and reinstall the b43 firmware now.

haha, I understand no worries. I was just trying all the different things that I found out there as nothing seemed to work and didn't really have much guidance. But that's different now, heh heh!...

haha, yup, I was reading up more and saw some more things that I could attempt to do and went ahead with playing around with the different things I found. Should I revert back to the previous update...

There shouldn't be much of a difference between the networks at work and at home as at work I'm trying to connect to my Verizon Jetpack MiFi and at home i'm connected to my own wireless router. It's...

New finding...somehow the WiFi works flawlessly, even after reboots and hibernation sessions, at home. Just got home from work to find that the WiFi was working the moment I signed in from home. Did...

The nomodeset worked for me when I was installing the OS on my mid 2010 macbook pro.
Another thing you can try is to remove the quite splash in the grub menu and just have that nomodeset there so...

No cigar from the last update I posted...

Decided to go ahead and wipe my previous 18.10 install and load with 18.04 LTS instead.
Got everything back to as they were when I was still on 18.10 but...

Quick update after a full day of usage yesterday...seems like the WiFi functionality has stabilized!

Rebooted the Macbook Pro several times and the WiFi was holding steady after all the reboots...

Another update with less than 20 min to go before its the New Year, woot woot!

Did another round of playing around and FINALLY got it! Well...I hope so at least, the WiFi has finally been holding...

The current dmesg situation:

$dmesg | grep wl

OK! Quick update!

Did some more research about this issue and tried out some new things! Was eventually able to finally get the WiFi to detect the wireless networks again to some success! ...

DOH! [insert facepalm] gah hahaha, what a pain...I guess i'll reload with Ubuntu 18.04 if this doesn't get resolved within the next couple of days then. Literally had to re-do this installation on...

Also, just noticed this...
