Hey everyone!
I'm a long time reader and lurker of SmallNetBuilder. I've long championed the high quality reviews and support of the community, and it has now come to that point where I could use some personal help and/or advice!
I'm a relatively advanced user of computers, being a helpdesk technician by trade, but I'd say a novice when it comes to networking. I have a fairly thorough understanding of the technologies, but no formal network training. I've dabbled in DD-WRT and other firmwares, and can explain to some degree the use-cases of most features on modern routers. However, I'm having trouble understanding an issue I'm experiencing, and wonder if I might get help brainstorming on possible solutions. While this isn't your average networking question, I do believe it has a root cause in some sort of network configuration, as my reasoning below will hopefully outline.
The issue is this: I have recently purchased a D-Link IP Camera, model DCS-930L. I have an e4200 Linksys router at home (v1), using a Thomson modem on TekSavvy cable internet in Ontario. I have installed this camera wirelessly in my home, and can access the unit without issue, intra-or extra-network. The only issue is using the myDlink Lite iphone application.
Here's where things gets weird.
The application crashes the moment I choose a webcam from my list in the application (crashes like any iphone app by vanishing instantly). Using it on my iPad 3 results in EXACTLY the same behaviour. This happens on 3G or WiFi. HOWEVER, there is a paid app for iPads only that will allow full use of the camera. It works perfectly, in and out of my home. This, in theory, should mean my network is fully capable and properly configured for everything to work. If this app was available on my iPhone, I'd swallow my pride and be happy but unfortunately only the mydlink lite app is available for the device.
Now here's some other interesting details:
Accessing the cameras of other people I know works perfectly without the crash! It seems only MY setup crashes the app.
The android version of the app accesses without issue!
If I bypass my router... it starts working perfectly!
SO: Considering all of the prior, it would seem to me that it can only be two issues: The app is crashing due to a response by my network (it shouldn't crash no matter what, but I'm not interested in solving the app problem, merely bypassing it by discovering the root networking issue), or my dlink profile is corrupted in some way.
A corrupted online profile seems unlikely, as I have recreated a new account and readded the camera from scratch, and the android version accesses the camera under the same account without fail. The network configuration issue seems likely, EXCEPT FOR ONE THING: if the camera is shut off, and I quickly try to access the camera (I literally shut down my entire network including router, except my modem [in hindsight I should have shut that off too in case it's somehow doing the bad response]), the app will still crash! The app somehow is still acting as a "buoy" of sorts, and maintaining the "Green-Light/Connection Possible" status in the app for maybe 1-5 minutes, and during that time, accessing it via the app still results in an app crash (you'd think if my network was sending a response it couldn't handle, it would just sit there trying to connect or have some other failure mode!).
Quite a wild issue and I would be deeply appreciative of any and all advice. Thanks in advance!!!
