I have an ICX7150-C12P switch that came with my lennar home and prior to its demise last year the wifi in my house was always unreliable. The unit is completely dead (no lights.. nothing). I tried connecting to it with instructions in other posts using my laptop but it won't connect at all. Is there any way to service these units or has there been any type of a recall or do I just need to give up and find new equipment?
