My setup is as follows:
1. T-Mo Home Internet + their gateway (url provided above)
2. Meraki MR56 (MVO - Cisco provided device) connecting to Cisco internal network (we seem to be working for the same company). Unfortunately, I can't provide more details as I"m just a user at the end of the pipeline. I've contacted our Cisco support and they pointed me to the T-Mo support. Same happened when I contacted T-Mo support, they redirected my request to Cisco.
Issue:
Once device is up, I can connect to SSID (Cisco internal SSID) and I can ping outside world. When I test the speed via speedtest.net, upload is 0 mbps, download is relatively fine (30-100mbps, depending on the time when I measure). Simple web pages would load (no javascripts etc) but when I need an interactivity on the line, I can't get anything back. Simple http://facebook.com fails to load.
