This is a weird issue, and I can't seem to figure it out. When I'm on my home network, I have really, really terrible lag with Facebook's mobile app *only on my phone*. I mean, it takes about 10 minutes for a pic to load. Any other app (on my phone) that connects to Facebook will lag really bad connecting to FB, as well. I've got Comcast and Speedtest will give me >100Mb/s on my desktop, hardwired to the router, and my phone will usually give me >50Mb/s. I've got an ASUS RT-N56U router, so I don't think that's the issue. I've tried both 5GHz and 2.4GHz, and they both have the same issue.
If I use the FB app on any other wifi network, or 4G, it works just fine. Any other tabs, iPhones, laptops, etc. work fine on my home network.
The thing is, it wasn't always like this... When I first got Comcast set up, everything worked fine. The problem seems to just have happened one day, and the only thing I changed on my phone was installing Transparent Weather Clock. Of course, I tried uninstalling it and seeing if anything changed, but no luck.
I am on 4.3 NB4, rooted.
Any help is appreciated! TIA!
