The antenna position may affect signal quality, currently my best antena position is vertical to exhaust panel (e.g. pointing outwards)

OK, thank you for the feedback.

It's not a lot. We're talking 100+ MB for several days worth of mining. I recently restarted my miner otherwise I would've given you some hard stats.

And whats your bandwidth usage?

Miner.php (in the official cgminer) will allow you to manage the pools if things are configured correctly, maybe try that?

Yes, no problems so far.
BTW: (how) is it possible to add more then 3 pools in avalon?
(and enable/disable it per clicking)

What's the bandwith usage of an Avalon with stratum? Anyone is using it under a 3g connection? Thanks.

Yes I do. There are far too many variables that come into play which can result in unreliability when it comes to wireless connectivity. So to sum up my opinions:

1) Mine with a stratum capable pool which has servers as close as possible to you (low latency)
2) Connect the miners via a wired connection to your home network
3) Ensure that you do not saturate the upstream of your internet connection. Even though the startum protocol is by FAR less bandwidth intense it is still a good idea to give it some room to breathe.
4) If you really want to get crazy setup QoS (quality of service) rules on your router to give higher priority to traffic coming and going on the typical bitcoin/stratum ports (like some gamers do with their games).

On a sidenote I would also recommend putting your router, dsl/cable modem, and ethernet switch (if you have one) on a UPS (battery backup). This should avoid damage from brownouts and other typical power fluctuations. Believe it or not some routers tend to lose their flash rom settings due to spikes in voltage and other electrical phenomenon. I doubt you'd want to come home and realize that your spiffy new money printing machine (aka Avalon) has been idle for 12 hours because your router crapped its pants and lost its mind.

Uptime is the name of the game here.

so you really think direct ethernet wiring of the Avalons to router will make a difference compared to wireless?  i think i've figured out a way to make that happen...

I would recommend not using getwork with this miner, stratum is IMHO the only way to go. It takes quite a lot to feed this monster and pools are not up to the task. There is the option of mining solo with it via your own locally hosted pool daemon, but you still need a beefy server to keep it well fed with getwork requests. I'm sure all the more technical users will explain all the nuances if you'd care to find out.

try Slush mining.bitcoin.cz  or ozco.in

the pools I choose are all with Stratum mining protocol supported

Maybe you need to try pools with Stratum mining protocol supported.

today i just got a new Asus Tomato router and noticed that my wireless signal quality to my gpu miners and server was down around 36-49.  any ideas how to raise that up?  boosting the transmission power didn't do anything.

I very much doubt it will have cron job support, but hopefully with it being a newer spec router it might be more reliable. Look into doing a wireless survey to see what channels are currently the most used (and therefore congested) in your area and change the router and your wireless client(s) to use the least occupied/congested channel. This will ensure greater signal stability.

Let us know how the new router goes.

Good luck!

thx
I have the TP-Link TL-MR3420 with latest firmware from TP-Link and I will try in next time openwrt to see if it is better...
I do not know if there is any option that TL-MR3420 is repeatenly (like cron job) checking for a connected device or how often this will be...
the router supports the 802.11n wireless standard and has 2 antennas.

Ouch. I feel your pain. I too am in a house with a similar age (a tad bit older actually) but I was lucky that a lot of the walls were renovated and they're now drywall based which is way way better. I guess one solution would be to run ethernet along the baseboard. It's fairly stealthy if done right.

To cheer you up, be thankful you're not living in a Faraday cage!

Many people are speculating on shipments, network difficulty etc, and although I didn't initially ever think I'd be in the mining game, I too am awaiting a Batch 3 shipment (85Gh/s + PSU). Since you can't order them anymore (sold out), I put up 50% of mine for auction here in case anyone wants to throw some change at it and limit their exposure. I started the bidding at 0.5 BTC per 1% of profit and it's already past 1 BTC in just a few hours, so I think the evidence is there that people believe having an only-ASIC market means not being a part of an ASIC buy will leave you in the cold. Well, not actual cold; those GPUs are very nice for heating a room!

I am in a 100 year old house with plaster walls, and a cistern.  Wireless won't propagate through the wall, even if the two antennas are only a foot apart.
