So I have two work laptops, one is backup to each other as I have bad experience working with Lenovo products in the past.
So today my laptop's battery got completely drained. And I plugged the laptop adapter , but no light or sign of life. Reset the pinhole behind it by removing battery and cable. No luck. So I thought it has died and went to turn on my t440p and it won't turn on either . Same issue, no sign of life.
I have no clue how to explain to my boss that both my laptops are not booting. He might assume I am lying to escape weekend work :'(
Edit: options I tried
Remove battery, power chord, reset pinhole and then power it on.
Try holding power button for 30 seconds with no power cord but battery inside.
so, I know that any broadcasts cannot traverse one vlan to another vlan. So for example if an access-point choose to connect to a controller it has to sent LWAPP discover broadcasts with in its vlan. For DHCP clients, they will be never be part of any subnet in first place ! I know we use IP helpers to let the dhcp hosts know where to find the dhcp server. How does these iphelpers function with L2 broadcasts ?
Back to wireless after 6 years. So was comparing the product line and saw quite a few changes, in fact a complete overhaul. Back when I last worked CAP3502I was considered fairly new when clean air was first introduced. And 1250 that supports a/b/g/n is the most widely used.
So what replaced cap3502i today ? and so 1250? It appears there are new technologies like wave1 and wave2 is the most significant difference. And rest of the AP series pretty much supporting all bands a/b/g/n including the ac. And only difference i see between these products is the spatial streams.
And do we need to upgrade the code on WLC to some later versions to support ac ? I dont see those radios on my 5508 controller with code (188.8.131.52). Thank you all.
