iPad iPad puts my Time Machine WiFi in panics

rfog · 05-15-2010, 06:44 AM

I've observed a serious problem when I turn on my iPad and do some internet stuff.

After that, I start having serious DHCP problems with my Time Machine Wifi. I use a lot of vmWare virtual machines to work and never had happened until I use the iPad.

After an iPad use, some virtual machines start to complain about IP conflicts...

It seems iPad does not send a "DCHP IP disconnection" (or wahtever command is) when switching off and on swith on it simply tries to use the old IP instead of asking a new one via DHCP...

I know it is the iPad network problem most iPads have, but with at least they must had tested with a Time Machine and it seems they don't. Very poor for Apple.

same problem Princeton reported moths ago. put your iPad on a static IP and problem solved

oh and apple has said something about a fix in a future os release, they didn't give a date though.

A side benefit for me of a using a static router IP is that I use that IP in a QOS rule to prioritize iPad access over other devices that might be in use in my house (xbox, ps3, desktop running utorrent, etc.)

makes it easier to do uploads to apps like GoodReader too, especially if you throw it into you local DNS

Now I've put a static IP in iPad, the IP conflicts seem solved but still sometimes when activating the iPad the network is not available and I have to go to configuration and activate it automatically. :-(

yeah, that's another bug apple has acknowledged. they suggest changing the brightness level in the ipad. i think it occurs if you have it all the way at the left side of the slider. move it up a bit. must be some sort of electrical interference.

Thats good to know, in fact I have given everything on my home network a static IP (What with two Iphones, two PC's, 3KG "Laptop" and soon to be an Ipad as well, they can get confused.

How is this going to effect use in Wifi Hotspots such as Starbucks, Hotels Etc? This is where I intend to use mine the most.

Each network has its own address rules. Your home network can be static and when you hit a hotspot it will grab a dhcp address.
