Android can kill your broadband. Or so I found out today.
Start to lose wifi this morning. Most devices losing internet access.
After rebooting router, all OK for a couple of mins, then trouble again. Reboot separate modem. Same problem.
Router showing high CPU usage on one core.
What the hell, upgrade router firmware. Problem reappears shortly after.
After a while, notice that Mrs Thor, who is home working, is not as disrupted as me. She has 5GHz wireless card in PC. I do not. Curious.
2.4GHz radio on router has gone screwy? Disable 2.4 GHz on router. Problem goes away. Hurrah. Except that most of my network clients don't have 5GHz capability :-(
With great difficulty, modify old BT home hub to act as 2.4GHz wireless access point, muttering to self that Netgear R7000s are too expensive to have to get a new one every 2 years. As soon as I plug home hub into router, problem reappears. 2.4GHz is off on router, but the same symptoms are appearing. WTF?!
Destroy BT home hub with lump hammer. Wasn't its fault, but I felt slightly better.
Change 2.4GHz network password on router, re-enable 2.4GHz radio. Start re-introducing 2.4GHz clients, PC first - OK, Android phone next - BLAM - problem reappears. My phone is killing my router?! Install virus checker on phone (via 3G mobile, cos phone only has 2.4GHz wifi and that kills the router). Virus checker finds nothing. "Have you tried turning the phone off and on again?" says Mrs Thor. So I do just that and all is normal again. This, at 4:30pm.
Android can kill your router. QED.
