I built my heater meter almost two years ago and have loved using it as often as i can. Last week I inexplicably lost wifi connection had to do a cook offline. The horror! My efforts to restore wifi have been unsuccessful.
I am using an Edimax EW-7811Un 150Mbps 11n Wi-Fi USB Adapter
I noticed that the wifi adapter was not lighting up. I did some searching on the forum and saw that an unseated memory card is a likely culprit. I opened the case and sure enough, the card was halfway out of its slot. Reseated the card, powered back up, and it looked like everything was fixed. At startup the wifi adapter lights up and blinks happily and the Heatermeter LCD reports that the network IP is the usual address (192.168.1.149 in my case, static). Unfortunately, I am still unable to raise the device from my PC at that address. Remote access to the HM was only possible via network cable on 192.168.200.1
Steps I have taken:
1) Deleted the wireless connection from OpenWrt and repeated the network setup instructions per the wiki. Setup went as expected (appeared to work) but I still cannot access the HM via wireless.
2) Downloaded the latest OpenWrt firmware image and wrote the image to the SD card. Reinstalled the card, booted up and repeated step 1. No joy.
3) Restored HM to original config reflashing the OpenWrt image (via System->Backup/Flash Firmware) and unchecking "keep configuration." Followed directions for wireless setup, which again went as expected but ultimately failed to allow me to access the HM at the IP address that is displayed on the HM at startup. Under the new software, i can at least access the HM via network cable without having to change my PC to the .200 subnet (which is nice, btw) but I'm out of ideas.
I haven't tried to ssh into the pi or to connect a display and keyboard and check things out that way. I'm a bit unfamiliar with those methods but will definitely give them a try if it gets me around this.
Any thoughts?
