We purchased a Samsung SCS 2U01 extender in 2014, attached it to our CABLE internet and it worked very well. No difficulty in start up or 3G function.
We have relocated to a home 1/2 mile away, where the Verizon signal is actually better, (2 bars rather 0-1). We are trying to attach the Samsung to a ADSL phone internet connection. Repeatedly trying: different Ethernet ports, (4 available on the wireless router (NetGear Wireless N-300), attache the port cable first and then power, waiting for HOURS. AND, placed the Samsung in a window to assure GPS signal availability.
All that comes up is a solid "Blue" indicator on POWER, and WAN, solid "red" on GPS and blinking "red" on SYS.
Spoke with Tier 2 Tech Support; asked that we first check with the ADSL provider (AT&T) to make sure the Ethernet ports are "unblocked". This is a rental home, and we don't have the account password for AT&T.
Other thoughts, in the event that the ports are "unblocked"??
