Yeah I'm having the same issue. It will literally stop tracking my path and not update with turn by turn directions until after I've already made my exit/turn in some cases. And I've got 4/5 bars on my signal strength so no issues there.

Fortunately most of the time this has happened I generally knew what direction to go/road to exit at, so I haven't been misled by the app yet but I could easily see it happening. I mean I literally got off an exit, when down almost a mile and made *ANOTHER* turn before waze instructed me to get off at the exit that I had gotten off at like 2 minutes earlier.

I suspect its definitely an ios 8 issue, because I NEVER had this issue before updating. Waze really needs to patch this problem because I'm just going to drop the app altogether if it keeps up.

Solution is very simple (thanks to @wazehelp): just hard reset the iPhone and voilá! I came to this forum looking for an answer on the same issue for my iPhone 5s running latest iOS and Waze versions, and trust me it works. (in case you don´t know: hard reset=press home and power buttons at the same time until the phone shuts down and reboots)

Same issue here. IOS 8.1. iPhone 4S.
All worked great until IOS 8 updates. Now I connect to network for about 5 minutes, get the route and current traffic to show, but then Waze drops network and never reconnects.

Please advise on fix!!!!!

I've been unable to use Waze for the last couple of days. All I get is searching for network even though I have four bars and 3G. Can't navigate anywhere as it can't find where I'm going. I've also tried deleting the app and reloading it. I've also deleted it of my iPad in case it was conflicting. Very frustrating

Great to not see it's specific to my phone, configurations or blame it on the iOS update. It's quite apparent this happened within the last 2 updates on Waze. I don't suffer loss of connectivity or GPS on other apps - including mapping/GPS ones.

I started noticing the (supposed) network loss. Everything you've experienced, I can attest to as well. Before I started noticing this distinct pattern, I posted something similar to this (or as a result of this). Do you suffer from any unusual data consumption as well? viewtopic.php?f=3&t=113993
