Wireless connection

Thu Mar 31, 2011 9:01 am

Is anyone else having issues with the wireless connection? I cannot seem to get my Blink to stay connected to (or even "see") my home wireless network. The router is located in the bedroom almost directly above the garage and I have really good signal strength in the garage itself. I did manage to get it connected once, but it needed a firmware update (actually two of them) and after the first one it rebooted and now I cannot get it connected again.

Ecotality says I may have to resort to a wired connection - which I'd really like to avoid for obvious reasons.

Any tricks? I thought about getting a wireless repeater that I could install in the garage itself or somewhere closer to the Blink, but I am not really sure that is the problem.

Can you plug it in just for the update? Then maybe it will connect on its own?

That's a good idea.

Our Blink is working fine over wireless. We did have a problem at install time with an obscure default firewall setting on our Belkin g router, not something I had set up. The Blink was able to obtain an IP address, but could not get further than that. Its connection attempts were logged in the router, which given the default setting interpreted them as a DoS "attack", which was how we eventually discovered the problem. After toggling the router setting (which again I was not aware existed to begin with), it connected fine and has been working since (about 250kWh of charging), aside from a couple of apparent reboots (based on the uptime being reset), from which it seems to recover on its own. We have firmware version L2R.1.2A, which was put in place by our installer before they brought the unit out. As noted it polls for new firmware every 15 minutes.

My Blink gave me lots of fits when I had a special character in my wireless SSID name. I took out the "&" character and went to straight alphanumerics and stability increased.

I haven't had any "failed to charge" incidents, but I WAS seeing the screen in 'calibrate' mode a lot and saw a lot of lost wifi symbols (black wifi symbol in lower right corner) even after I removed the "&" character from my SSID. SO, as a test to see if these problems are wifi related (and I'm assuming they ARE), I hardwired my Blink this morning. It's now up and running on the LAN, so we'll see if I see any more of those random 'calibrate' screens.

I was able to run 50' of CAT5e cable plus associated jacks, etc., for just under $50. For me, it is worth the time and effort if I can help Blink put out a better product. I shouldn't HAVE to do this, but I think the Blink unit is head and shoulders above the Clipper Creek unit and I want to see this type of EVSE become the standard, not something that is brushed aside because it was too buggy.

I'll report back here as time goes on regarding the stability of my unit on the LAN. I can already say that the intranet connection data runs MUCH faster. I'm guessing the Blink designers took an 'off-the-shelf' wifi setup and threw it in, not fully understanding all the intricacies that go along with it. (shrug)

If the antenna on your router is vertical, being directly under or over it can be a problem. Doubly so if the Blink's antenna is configured the same. You might try rotating the one on your router more horizontal as a test.

I installed a wireless extender to the garage, and then connected the blink to the extender via a wired connection. It's been working fine since, save one crash during the violent rainstorm 2 weeks ago.

I used a couple of ethernet-over-powerline modules to get mine "hard wired" enough to update its firmware. After I did, I noticed that the Blink could see my wireless (it failed to before). Haven't tried reconfiguring to use the wireless yet.

Might go to an E4200 (new) router soon, it's supposed to have twice the 2.4GHz range of the Valet I'm using now.

Update:

Hardwired my Blink this morning. I didn't see a 'lost internet connection' all day, so I was hopeful everything was A-OK. Blink charging timer set for 11pm-7am 7 days a week.

I plugged my Leaf in just before 9 tonight and the unit automatically started charging. (even though the screen said "next charge will occur at 11pm")

At least your on Level2. My Blink is still dark and my Leaf won't be charged fully on Level 1 by morning. I just hope it's enough.

Good news is..I'm leaving the A/C off in attempt to avoid the other issue so I'll have a bit more range :lol:

I have a Linksys wireless router I purchased a few years ago and it has two external dipoles. It's located in the office and we use our notebooks in the family room, which is about 60 feet and three walls away. I kept loosing signal and the throughput was horrible. My solution was to construct a couple 9 dBi gain parabolic reflectors to slip over the dipoles. After doing this my signal strength in the family room jumped to 90%! The Blink is 70 feet from the wireless router and is behind four walls. The signal strength at that location is presently 80%. It takes about 20 minutes to construct these parabolic reflectors. You just need some cardboard, aluminum foil, glue (spray glue is best), a printer to print the template and a pair of scissors. Here's a website with the template and directions. The beauty of this solution is that I didn't need to purchase and configure a range extender, your WiFi signal is focused where you need it, it's passive so there's nothing to fail, and it's cheap.
