ZTE LTE wf830 Router Troubleshooting: Internet Hangs, Band Settings, & Antenna Placement Tips

Force the LTE bands one at a time with aggregation turned off first, and test bands 1, 3, 7 and 20 separately; the WF830 can aggregate only two bands, so this helps reveal which band pair actually works best [#18978938] The thread’s main finding is that the automatic setup often locks onto weak LTE2600 (band 7), which can make the connection unstable, so disabling band 7 and using a simpler 1+3 or 2100/1800 configuration may stop the router from hanging [#18982937][#19321480][#19323188] For antenna placement, move it higher if possible, ideally to the roof/chimney, aim it at the BTS, and compare signal values like RSRP and SINR; the posted readings of around -100 dBm, SINR -2 dB and RSRQ -15 dB were considered poor, and trees on the path can still hurt reception [#18983418][#18983667] If the current balcony position is already on the same side as the BTS, moving to the chimney may not help much, but if the path is obstructed it is worth testing there and taking screenshots for each band setting [#18982937][#18983418][#18983667] The WF830’s built-in antenna was also described as having too wide a beam and too little gain for this location, so if you want the best practical result, a different router such as a B818 plus a high-gain dual LTE1800-2600 antenna was suggested [#18984895]
