EX7500 can not access web interface after firmware upgrade

Same thing happened to me this past weekend. I saw an update and decided to do it as I was starting to have some connection issues to the extender. The update locked up and I now hav a $200 brick!! Called support and they told me to factory reset and re install which I have already done 8 times now. I STILL cannot get it to connect to the Internet properly and cannot see the log in page (www.wifiext.local). I am out of support warranty by a couple of months but still have hardware warranty. This company has not been very helpful at all with this isssue. something happened during the firmware update and my externder is screwed!!
