I am not sure whether this question should be on Server Fault or on Network Engineering. In order to ask my question, I first need to describe the problem I am facing:
Say I have a LAN
10.0.0.0/24 and the router is at
10.0.0.1 (the router is not a wireless router, it only has Ethernet ports). I have a wireless access point (WAP) at
10.0.0.5, which broadcasts two SSID at 2.4 Ghz and 5 Ghz (say
AP5G), both on the same LAN. The WAP is connected to the router by Ethernet.
I installed a wireless (-only) printer at a static IP on
10.0.0.6. Because of a hardware limitation, it can only connect to 2.4 GHz radio bands (and thus it cannot connect to 5 GHz bands). So the printer is on the
Here is the thing: I realized that from a wireless device (whether a phone or laptop) I could not access (not even ping) the printer if my wireless client device was on the
AP5G; however, as soon as I would connect my wireless client device to the
AP24G, I could access the printer. Also, I saw that from the router, I can ping without any problem the printer.
How is that possible? To me, the frequency/SSID should not be a problem as long as the devices are on the same LAN. Even more so, the router can access (ping) the printer. Or could it be a problem from my access point (Linksys LAPAC1200)?
Thank you in advance.
