Essentially it will be configuring DD WRT to disconnect/dissociate/not let them connect in the first place automatically any client whose signal drops/or is below an administrator-defined threshold (eg. RF signal strength and or SNR). Having a few clients stuck on the first access point they see and not letting go is causing me a big problem. This is a large WDS spoke and wheel setup. I have examples of ubiquity scripts similar to what I'm looking for. I know there is other equipment out there that can easily manage this but I need to keep the ubiquity/ddwrt hardware in place. I will need to upload this script to about 15 access points.

I am the owner of, a Virtual Private Server provider that provides servers with <1ms ping to sneaker retailers. This allows users to access the limited release sneaker such as Yeezy's extremely quickly with their bot so that they can purchase pairs. To compliment my servers I am hoping to sell proxies as well, much like these ones They will be hosted in the same data center as my servers in an effort to provide the best possible latency to sneaker retailers wesbites. - These proxies must be as fast as possible (when using my servers they must not receive latency to sneaker retailers above 100ms) - I would like to be walked through the setup process as well or given instructions so that if something goes wrong I can fix something. And I like learning I will not reply to generic bids which do not address this specific project. Thanks.

I have been working on Openwrt devices that we heavily modify for our purpose & setup at their client location. We have started to spend time setting up a testbed which could stress test our routers (& newer versions of it) with the actual work that a network client does - connect with the router (DHCP), do network jobs like downloading/uploading data, disconnect & go away. All these network clients are inside a PC & I do not want an 'expensive docker/VM' setup. All these clients should be able to run on command line or through a bash script that fires multiple of them. A good start point that I have identified is . This small piece of code can test DHCP server of our router running from the PC. Multiple of these can be fired simultaneously. I also looked at which does TCP-IP job from command line but I could not figure out an easy way to extend dhtest with this. In final setup - I should be able to create a text file with each line as a task. Something like download upload . . When a network client is spawned, it should first obtain IP address through DHCP (which is what dhtest is doing), then start following the file to do the job one by one. All job completion should be logged in completion.log with time taken to complete the job. Any error (during dhcp or file download/upload case) should be logged in error.log with the error reason. Please ensure that multiple of these programs could be launched simulatenously & they should obtain their own IP address & do the job listed in the file independently. Bonus: If you are able to also create a provision of writing a wrapper script that takes number of clients to be launched & then launches them in background- that would be bonus. That plus if you able to do this whole project within 3 days, I am willing to throw in additional $25. Please note, 3 days is not the first turn-around. You should ideally be able to wind it all up within a day or max 2. 3rd day is kept for testing & reporting any issue.
