<div dir="ltr"><div><div><div><div>Here is a followup on the issue.<br><br></div><div>First
regarding JJ's post. The issue is not 'reception'. The issue is
'coverage', 'strength', and 'stability'. The backyard had some coverage, but it is weak and intermittent. Not a stable connection for what I want to do (basically control a camera connected to a telescope). The WiFi router is in the
basement, and perhaps blocked by the concrete walls, and/or the I beams
interfering. So the solution I had in mind from the beginning is to have another AP station upstairs
closer to the back of the house, and higher up, rather than in the centre of the
basement.<br><br></div><div>Now for what ended up working for my case:<br><br></div>I got
another router, put OpenWRT 15.05.1 on it and connected it to an
ethernet cable that runs from the basement (where the main router is).
The connection is via one of the LAN ports, not the WAN port.<br><br></div>I put a separate SSID on it, and gave it an address on the same subnet. <br><br></div><div>Then disabled DHCP and the Firewall on it.<br><br></div><div>The basic steps are under the Web LuCI section here:<br><br><a href="https://wiki.openwrt.org/doc/recipes/dumbap">https://wiki.openwrt.org/doc/recipes/dumbap</a><br><br></div><div>The only thing that I added to the above steps is add the main router's IP as a default gateway.<br><br></div>It
works well. There is good coverage for the far end of backyard. And this is done without having to deal
with outdoor cables, nor run a cable up and another down and move the
main router to the main floor, and get a UPS for it. <br><br></div><div><div><div><div>For
the sake of completeness, I am listing other stuff that found on
OpenWRT. None of them do what I want, but related in case someone needs
it.<br><br></div></div></div>There is a whole bunch of info in the
recipes section of OpenWRT's wiki, with relayd, routed, bridged, ...etc.

<div>WiFi reception in my house, using the OpenWRT powered D-Link DIR-835, is generally adequate, but could be better in some spots. Reception is intermittent in the backyard, where I am pondering a project that would need it. Perhaps the basement's concrete is interfering?<br><br></div>
<div>I like OpenWRT and plan to stay with it. Also the router itself has lots of storage (flash) and RAM, so will be here for the future. It is in the basement, near the cable modem, and other equipment, and connected to the UPS in there. <br><br>Moving it to the main floor is not likely since it would involve finding a power outlet and running Ethernet, as well as losing the UPS connection.<br><br></div>
So, my questions are:<br><br></div>
1. What does one do in this case? Do you buy another router, possibly one capable of running OpenWRT and turn off the router features, and keep it only as a WiFi hotspot and put it near the spots where good reception is needed?<br clear="all">
<div>
<div>
<div>
<div> </div>
<div>2. If so, what are good routers that you tried this on?<br><br></div>
<div>3. How did you turn off OpenWRT routing ...etc. on it?<br><br></div>
<div>4. Does the new WiFi hotspot have its own SSID or can it use the same SSID as the main router?<br><br></div>
<div>Any other thoughts/ideas welcome.</div>
