Standard Netgear wifi router with standard config. As I said, it's fine except when Apple devices come onto the network.

I'd suggest that it warrants more investigation than just writing it off as Apple trashes networks. Hybrid Apple/Windows households have been common for the larger part of 2 decades now and certainly others do not experience the same issues guaranteed. So rather, the title would be Apple devices cause issues on your home network. Or more accurately, something on your home network works in an unintended fashion when y…

It's not just his iPhone. It's iPads, any Apple device that has been "away" for a while and then comes back.

TFA describes how Apple is taking shortcuts in the DHCP negotiation. I blame them for assuming that the previous IP address assigned to the device will still be available.

Could have been titled: How do Apple devices wreak havoc on home networks. When my kid comes home with his iPhone there is a better than even chance that my home network will go out to lunch. Router reboot time. Never happens with Windows or Android devices coming and going.

This is a known issue on iOS 8.0-8.1. Lookup 'WiFried'.

I'm a bit disappointed that you're downvoted to grey right now because editing obscure config files and entering esoteric terminal commands is exactly why Linux is so difficult for the average user, and it's never going to improve if those who're already comfortable with it ignore the problem.

That's all fine and dandy for the desktop case. But its a dhcp server , network admins would be expected to touch config files, and the interface for a DHCP server really can't be much worse than the GUI version that microsoft supplies! but digressions, to say "this is why I won't use a linux desktop" in response to a server-specific use-case, is at best antagonistic!

Pfsense does a great job offering a GUI for how configuring DHCP should work.

My SO unfortunately has 2 ipones, an ipad and a MBP. There is a confluence of DHCP activity from all these devices that is guaranteed to take my network down.

Odds are high that GP's router is configured to give out addresses sequentially, with a fairly short lease and the wireless ap is configured to disallow communication between wireless hosts. I'm thinking the odds they'll change the configuration vs yell about apple devices aren't so high.

Rapid driving: how ignoring red lights makes the iCar so fast.

As I was reading, I was mentally composing a convoluted reply. Yours said the same thing, much better, and bonus coffee over my screen! well done :)

> bonus coffee over my screen

Why did you pour coffee on your screen? That's really quite strange behaviour.

The used netgear router a friend gave me, does a fine job of getting my devices ip addresses on time without me touching the config.
