I've a problem with Netplan not connecting to WiFi network with hidden SSID. It works great if I'll make this network visible. But no chance with hidden one. Any options to configure that?

I need to configure my wireless router so all wireless devices are on a different subnet (192.168.2.1).  The wireless devices should be able to access the internet, but ideally not the workstations on the LAN.  Here is my network:    All suggestions welcome!

I plan to install Ubuntu soon on my PC. I currently use a TP-LINK TL-WN822N wireless adapter. I want to know if it will work without additional setup.

I booted Ubuntu 17.04 live on my Fujitsu Amilo Li3710 laptop and I was surprised to see that I couldn't connect to wifi. I tried to connect to my router and my phone as a hotspot but neither work.  I can see wifi networks and when I try to connect it asks for the password, seemingly tries to connect but then it doesn't connect. It gives no visible feedback after failed trials.  Disabling mac filtering and removing the wifi password makes no difference. I tried Ubuntu, Ubuntu Gnome, Ubuintu MATE and Lubuntu, it's the same everywhere.  I have Ubuntu 16.10 and Windows 10 installed on the laptop, they have no problem connecting.  Is there anything I can do? Or is support for my hardware over in the kernel?

I have a Macbook running Mac OS X, and I have Ubuntu running in VirtualBox.  I am using a public WiFi network on my Macbook, but for some reason my Ubuntu virtual machine won't detect it.  It was able to detect public WiFi networks before, but now it can't.  The network just isn't showing up in the network menu.  How can I fix this problem?

I'd like to install OpenWRT on an Asus WL-520GU router I have a couple of Asus WL-520GU modems and Raspberry Pi (model B) boards floating around and I'd like to put some of them to use in some capacity around my  network. I want to install OpenWRT and would prefer to use one of the Asus boxes. Actually, one already has an old release from 2008 on it—but I'd like to upgrade it to the latest as at the writing of this, 15.05. But I'm not quite understanding the compatibility of these devices in relation to the &quot;Current Release Support&quot; you see on various pages. From the  search page for the device page for the , it appears the latest support version is 10.03.1 Also in relation to the Raspberry Pi (model B), ( and  pages), it would appear the latest supported version is 14.07. My question is: What is exactly meant by Current Release on the  page? Confusion: What I'm confused about: will Chaos Calmer run on these devices? My thinking:  YES. It's really a matter of building/compiling the package (unsure of exact terminology) for the device you're using. Maybe, (or it probably will), it's just that no-one has compiled it for these yet or that maybe someone has tried and were unsuccessful, gave up and moved on, and so with a little extra work/research it possibly could work No. That chipset, memory, other some other feature of the board is no longer supported and it will cause too many headaches to move on.  Just some of the notes I've made about it:  WiFi/radio issues—not working in kernel 2.6, but worked in  2.4, what about 3+? —USB and wireless, doesn't seem insurmountable —various stuff including the page stops at Attitue Adjustment and Barrier Breaker. There's no mention of Chaos Calmer at all The one that has something installed is Kamakazi (unsure what version, but release 12857, so it's a bit old) I'm aware I can get and use 10.03.1 from the  if that is as far as I can go I am aware of another question (which is from 2011), although he's using the Asus WL-520GU as well, it's about an  because of the 2.6 kernel problem, which AFAIK remains unanswered for later distros  Finally I'm not scared to get in there and give it a go (I really don't have much idea as to what I'm doing with building/compiling these sorts of things, but I'm adventurous) :) but I don't want to waste my time either if it's a definite 'no go'.

Can anyone assist with a linux routing question? Essentially I want to use an Ubuntu laptop to provide internet access to an attached network.  I have a Raspberry pi on a wifi network (192.168.42.0/24). Its ip address is 192.168.42.20.   Internet access is provided by a cell phone hotspot. (192.168.43.0/24). The internet gateway is 192.168.43.1  I have a linux laptop (Ubuntu) with two wifi cards - one on each of the above networks. (192.168.42.21 &amp; 192.168.43.10)  I also have another network connected on the ethernet card which successfully shares the internet connection with clients. This network is 10.42.0.0/24.  The laptop is a DHCP server in this case and its ip is 10.42.0.1  I am trying to use the laptop to provide an internet access route for the Pi I have added the following iptable rules to the laptop. They are derived from the forwarding rules for the 10.42.0./24 network which as I say can connect to the internet.  -A FORWARD -d 192.168.42.0/24 -o wlx801f0281f02a -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -s 192.168.42.0/24 -i wlx801f0281f02a -j ACCEPT -A FORWARD -i wlx801f0281f02a -o wlx801f0281f02a -j ACCEPT ip_forwarding is enabled   I have added a route on the Pi. The route table now reads:  Kernel IP routing table Destination     Gateway         Genmask         Flags Metric Ref    Use Iface 0.0.0.0         192.168.42.21   0.0.0.0         UG    0      0        0 wlan0 192.168.42.0    0.0.0.0         255.255.255.0   U     303    0        0 wlan0   The Pi can ping through to both the other networks and both other networks can ping through to the Pi.  BUT ... the Pi still doesn't have internet access, although a device on the 10.42.0.117 happily reaches the outside world.  The routing table on 10.42.0.117 is exactly "parallel" to the Pi's:  Kernel IP routing table Destination     Gateway         Genmask         Flags Metric Ref    Use Iface 0.0.0.0         10.42.0.1       0.0.0.0         UG    0      0        0 eth0 10.42.0.0       0.0.0.0         255.255.255.0   U     0      0        0 eth0 127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo   What am I missing?

I'm soon going to be setting up a wireless network for me and some buddies and (hopefully) making it secure. I have some questions and concerns regarding this and figured someone here could give me a hand and steer me in the right direction.   I have a WRT55AG (version 2) loaded with the factory firmware. I've heard that it's possible to load your own firmware onto routers like these. Is it worth it? What can be achieved with it? I was wondering what kind of security I should use on my wireless. Ideally I would want all devices to be 'accepted', but I'm not sure how to accomplish this. I'm guessing it has something to do with MAC addresses, but I don't know the first thing about them. It would be great that ALONG WITH encryption (I'm told WPA2 is the best), every device would need to be added to a list of some sort before even being able to access the AP. Another feature I was thinking of would be completely hiding my wireless from showing up on other people's computer. Is this possible (like an SSID broadcast thing). Is it worth the trouble? One more option I was looking to implement would be bandwidth calculators. Ideally something in the router to measure the amount of bandwidth being used and how much has been used for that month (this has to do with bills and limits, obviously). Is it possible to throttle down speed when a certain limit is reached?   These are alot of points but I was hoping someone who has more knowledge than me in this subject could give me a hand and a few pointers. Hopefully all this is possible and I'm not dreaming :)

How should Kerberos authentication be set up with IPv6?     What implications are there when client devices each use a public, globally routeable IPv6 IP address?  What changes when setup this way instead of using a NAT as was the norm with IPv4?

So I just started using linux/ubuntu today and I've been getting problems with my wifi, ive tried the solutions on this page:  When im really close to my router, its fine, i can see wifi signals, but when i go just a few steps back it disappears right away. Im using the latest version of ubuntu 17.10  Any suggestions would be nice! :)

Goal: I want to be able to securely use the internet via my home PC while my notebook is connected to an open hotspot/access point.  I do know that I can use a SSH tunnel/SOCKS proxy, but I don't want to fiddle around with applications (making them use it, if even possible). I guess what I need is an OpenVPN setup, so I'm looking for a detailed guide on how to:   Install and setup the OpenVPN server Setup the OpenVPN client (NetworkManager)   Ubuntu versions this should work on are 10.10 and 11.04.
