Instant On - Wireless

Hello,

I have two AP-11Ds, one in the utility closet where the WAN comes in, and another in the den hardwired to it. They both are configured with a WiFi main "employee network" and a guest network. All my WiFi devices (about 20) are connected to the main network SSID, including an HP OfficeJet Pro 8720 printer. In the den I have an Acer Chromebook Spin 13 which is connected via WiFi to the main network SSID and simultaneously hardwired to the den AP-11D; it preferentially uses the wired network.

The problem is that the Chromebook often loses connectivity to the printer, saying "Not connected to printer". When that happens, I unplug the Ethernet cable from the Chromebook, let it fall back to WiFi, and then it works. My question is, do I have to somehow configure the AP-11D wired LAN ports to access the main wireless SSID so they're on the same network? A similar situation exists with my LG smart TV (hardwired to the utility closet AP-11D) when I try to pair it with the LG app on my phone (on the main WiFi SSID); apparently that's not considered "on the same network". Or is there something else keeping a computer on a LAN port from being able to see a printer on a WiFi network?

Are you using the AP-11D in the Utility Room as a router?  Or is there a separate router on the WAN connection, and both AP-11Ds are just operating as Access Points, and wired to the same IP subnet on the separate router?

It makes a difference, so that needs to be clarified first.  With a setup like you have, I would personally have a router connected to the WAN, and either use its internal switch ports, or a small external switch connected to the LAN side of the router, and connect both AP-11Ds to the switch ports or external switch.

Also, is your Guest network on a separate IP subnet than your main network?  If so, what does the routing between the two?

Does the Chromebook "know" about both the main wireless SSID as well as the Guest wireless SSID, and is set up to automatically connect to either one?  If so, then maybe it's switching SSIDs and getting onto the wrong network.  I would suggest only having the Chromebook know about one WiFi network.  If you want it to have both SSIDs available, then set the preferred one to automatically connect, and set the other one to connect manually.

As far as using the Chromebook with both a wired as well as a wireless connection at the same time, you should probably go into network settings, if possible, and set the non-preferred connection (wired or wireless) with a worse metric for the default route, so when both are connected it will use the network connection with the better default route metric, and fall back to the other one when the preferred connection is gone.

Hi Dhanasekar,

Den AP port E1 (the Chromebook) is assigned to untagged network "(management) VLAN 1". The printer is connected to the main WiFi on the Den AP, which is assigned to "VLAN 1". Is that the information you're looking for? 

I don't understand the difference between "tagged" and "untagged", but the Aruba Instant On app doesn't let me change it.

Hi Busirane, 

Yes, thanks. as you confirmed they both are in Management VLAN 1 then the printing should work even when connected via wire

And that's the heart of my question: why doesn't it? If I unplug the Ethernet from the Chromebook, then it works. 

I'm not above blaming HP; there's an unrelated failure mode where the printer somehow gets an IP address on a completely different network. The fix for that is to toggle the printer's WiFi off and back on, then it gets a good IP. For that failure, I wonder if the so-called HP Dumb^H^H^H^HSmart app is to blame.

That's very odd behavior.  Does the other network that your printer receives an IP address on even exist in your environment?  Or is it getting a Link Local 169.254.x.x/16 address because it received no response to its DHCP request?  If so, you have other issues in your network.

My network connection "philosophy" is to hard wire anything that has the option for a wired connection and doesn't move (AppleTV, smart TV, printers, desktop computers, laptop computers that remain in one place) and leave wireless for mobile devices (smart phones, tablets, laptops, smart home devices).  And NEVER set up a device to use both Wired and Wireless NICs at the same time.

For the few devices I have that can use both Wired or Wireless network connections, I always set the Wireless NIC to not auto connect or auto login to the Wireless network.  So, at the time of connection, whether Wired or Wireless, I decide which connection to use; the device doesn't decide.

A similar situation exists with my LG smart TV (hardwired to the utility closet AP-11D) when I try to pair it with the LG app on my phone (on the main WiFi SSID); apparently that's not considered "on the same network". Or is there something else keeping a computer on a LAN port from being able to see a printer on a WiFi network?

I had to wait until it happened again but, yes, the printer does sometimes get a 169.254.X.X address. Toggling the printer WiFi off and on again fixes it. What "other issues" in my network might that indicate?

Regardless, I don't think that's the same problem as not being able to print from my wired Chromebook, even when the printer's IP is correct. My fix for now is to simply keep the Chromebook on WiFi instead of wired. I'm not doing anything data intensive enough to demand a wired connection.

That's very odd behavior.  Does the other network that your printer receives an IP address on even exist in your environment?  Or is it getting a Link Local 169.254.x.x/16 address because it received no response to its DHCP request?  If so, you have other issues in your network.

My network connection "philosophy" is to hard wire anything that has the option for a wired connection and doesn't move (AppleTV, smart TV, printers, desktop computers, laptop computers that remain in one place) and leave wireless for mobile devices (smart phones, tablets, laptops, smart home devices).  And NEVER set up a device to use both Wired and Wireless NICs at the same time.

For the few devices I have that can use both Wired or Wireless network connections, I always set the Wireless NIC to not auto connect or auto login to the Wireless network.  So, at the time of connection, whether Wired or Wireless, I decide which connection to use; the device doesn't decide.

And that's the heart of my question: why doesn't it? If I unplug the Ethernet from the Chromebook, then it works. 

I'm not above blaming HP; there's an unrelated failure mode where the printer somehow gets an IP address on a completely different network. The fix for that is to toggle the printer's WiFi off and back on, then it gets a good IP. For that failure, I wonder if the so-called HP Dumb^H^H^H^HSmart app is to blame.

Hi Busirane, 

Yes, thanks. as you confirmed they both are in Management VLAN 1 then the printing should work even when connected via wire

Hi Dhanasekar,

Den AP port E1 (the Chromebook) is assigned to untagged network "(management) VLAN 1". The printer is connected to the main WiFi on the Den AP, which is assigned to "VLAN 1". Is that the information you're looking for? 

I don't understand the difference between "tagged" and "untagged", but the Aruba Instant On app doesn't let me change it.

Hi Busirane, 

Please check the wired port configuration of the Den AP where Chromebook is connected.

is it on the same VLAN as your printer, are they reachable

Do I need to configure the Den AP (at the bottom in the topology diagram) as a router too, instead of just as an AP?

Are you using the AP-11D in the Utility Room as a router?  Or is there a separate router on the WAN connection, and both AP-11Ds are just operating as Access Points, and wired to the same IP subnet on the separate router?

It makes a difference, so that needs to be clarified first.  With a setup like you have, I would personally have a router connected to the WAN, and either use its internal switch ports, or a small external switch connected to the LAN side of the router, and connect both AP-11Ds to the switch ports or external switch.

Also, is your Guest network on a separate IP subnet than your main network?  If so, what does the routing between the two?

Does the Chromebook "know" about both the main wireless SSID as well as the Guest wireless SSID, and is set up to automatically connect to either one?  If so, then maybe it's switching SSIDs and getting onto the wrong network.  I would suggest only having the Chromebook know about one WiFi network.  If you want it to have both SSIDs available, then set the preferred one to automatically connect, and set the other one to connect manually.

As far as using the Chromebook with both a wired as well as a wireless connection at the same time, you should probably go into network settings, if possible, and set the non-preferred connection (wired or wireless) with a worse metric for the default route, so when both are connected it will use the network connection with the better default route metric, and fall back to the other one when the preferred connection is gone.

Hello,

I have two AP-11Ds, one in the utility closet where the WAN comes in, and another in the den hardwired to it. They both are configured with a WiFi main "employee network" and a guest network. All my WiFi devices (about 20) are connected to the main network SSID, including an HP OfficeJet Pro 8720 printer. In the den I have an Acer Chromebook Spin 13 which is connected via WiFi to the main network SSID and simultaneously hardwired to the den AP-11D; it preferentially uses the wired network.

The problem is that the Chromebook often loses connectivity to the printer, saying "Not connected to printer". When that happens, I unplug the Ethernet cable from the Chromebook, let it fall back to WiFi, and then it works. My question is, do I have to somehow configure the AP-11D wired LAN ports to access the main wireless SSID so they're on the same network? A similar situation exists with my LG smart TV (hardwired to the utility closet AP-11D) when I try to pair it with the LG app on my phone (on the main WiFi SSID); apparently that's not considered "on the same network".
