Some requirements given a priori and I can not change,(customers location and service availability) so please stick to the question, not hypothetical suggestions. Given - Verizon Jetpack as i-net access, only WiFi connection available. Need to find router which will use that signal as WAN. Presently I am debating ASUS RT-N56U, RT-AC66U, or RT-AC68P. So may be someone already done it before? Any particulars will be appreciated. Another possibility is to use DD-WRT on linksys router in repeater-bridge mode, but my previous experiences wasn't very successful. Any (preferably) working configurations anyone can suggest?
