Glenn:  Wonder if a block name change is in order?  What threw us for a curve is the SSID which for me is a number after your callsign aka the old packet days.  Wonder if changing that block to NETID or something that might not lead an old guy off on a wild goose chase?

Thanks for you help!!!

Thank You Glenn!

["Boot_wait" off by default on these routers, so you should turn it on, see OpenWrtDocs/BootWait.]

 If I click this link, the webpage says the topic does not exist yet.

How do I access this boot_wait option? Should I upgrade firmware first, or switch boot_wait on first?

Thank You, Trent KJ4KAF

I received funding for some links to study "Network Survivability of Distributed Decentralized Networks". We are looking at network survivability defined as being able to transfer "useful" amounts of data for emergency comms rather than restoring full network capability.  Basically, we're going to measure latency, throughput and connectivity on a network like I described in the earlier post and try to determine what the minimums are for useful communication.  I'll the posts here updated if anyone is interested.

We have been taking a bit different approach here.  We're using 5.7Ghz 802.11n for backbone links using directional antennas but keeping the patterns pretty broad by using backfire or panel antennas (17 to 20dBi at 90 or 120 degrees).  The goal is to multiply connect the nodes and let either OSPF, some form of meshing or both handle connectivity changes.  The idea is for these links to be able to take a fair amount of shaking and still be reasonably aligned.  These links are operated as part 15 devices so we don't have restrictions on encryption, etc.  We control access to these tightly.  We can make this work very reliably at fairly high transfer rates (32Mbs) over paths up to 25 miles though we're trying to keep most to 20 miles for fade margin purposes.  These connect Access Nodes on 2.4Ghz 802.11g/n that use omnis (12 - 15dBi) or multiple panel antennas (15 to 17dBi) to provide user access.  Still working on the ranges for the access nodes but reliable omni range should be in the 3-5 mile range using omnis and up to 15 miles using grids or backfire antennas.

Both nodes list each other on the WiFi list as does my laptop using it's WiFi.  I might add that

both are WRT54's one is a ver 2 and the other a ver 1.1.

Open WRT talks about taking the router apart. I don't understand what this is about. It mentions an unpopulated 10 pin header with 2 serial connections, and a DB9 connector. Is this part of HSMM-mesh or something else. I thought my laptop would connect through the Network cat5 cable.

Thank You Trent KJ4kKAF

thank you very much for the prompt reply. I'm not at the building stage yet but until I found this site, I always wondered the answer to that question. Then couple that with reading questions and answers on the auctions like I did on one of them today on Ebay where the person asked what the first digits of the serial number were- caused me to wonder just exactly how much it mattered, or if you got the wrt54gl that was good enough, regardless of the serial. Thanks, James
