Had some major issues getting an iPad2 to play nicely with D-Link’s DIR-615 (Wireless N300) router. The symptoms were curious. First, when browsing updates on the App Store, some app icons would not show up (instead, replaced with a question mark.) Second, when running the CTV video app, the framework seemed to work fine, but the content for ‘latest videos’ would not show up at all. The rest of the app seemed to be okay. Third, when trying to update Apps, I’d often get a timeout with an error stating that the iPad “could not download it at this time” or something like that. A tap to retry would get the same error.
Soooo…a few random changes on the router. Tried changing the security type (WEP, WPA, WPA2) and tried adjusting firewall settings. Nothing. I’d occasionally get an app to download, but the CTV app became my ‘Canary‘, telling me that something was still wrong. Data wasn’t completely blocked, just not routing correctly.
The final fix seems to have been changing my DNS servers (set by the modem via Cogeco) to Google’s Public DNS servers. The easy-to-remember 22.214.171.124 and 126.96.36.199 became the new primary/secondary servers. After that change, things seem to be working correctly. It seems that CTV’s app was mostly an HTML page, and the content for the ‘latest videos’ section was pulled from somewhere entirely different that was not agreeing with any DNS lookups…?
Anyway, seems like this router will stick around for now.
On a similar router-related issue. It seems that you can’t rely on a routers ‘auto-detect’ for wireless channels. It seems I was having some major issues in my apartment recently, and I figured it was tied to the large number of WiFi broadcasting going on in the area. Similarly, the number of phones using the 2.4ghz range wasn’t helping. The auto-detect was not finding the best channel, and manually setting it to a channel seemed to fix the problem.
