I am a senior recovery engineer for enterprise storage systems. The team I'm on deals with complex problems and long term recovery solutions in varied and complex environments. What this means is that the average issue deals with data inaccessibility and/or loss and requires immediate attention and relief of symptoms often times followed by long term actions plans in order to mitigate further issues and bring the environment back to a healthy state. I work directly between support and post release in order to manage escalations and provide time-sensitive results to code issues.

While my specialization is in networking (TCP/IP,pcap analysis, infiniband, DNS, etc), I also utilize skills in file system management (ntfs/*nix/mixed perms, corruption, data layout), authentication and directory services (NIS/LDAP/AD), hardware diagnostics, custom scripting (Bash/Perl/Python), log file analysis, C code debugging, backup and restore and statistical analysis.

I tinker with Bash, VB.net, Python, Perl, Autoit, C and and SQL in my spare time.
I used to be a Telecommunications Specialist (VoIP, Data, Infrastructure).
My degree is in Classical Numismatics and Archaeology.

comment Telnet cannot connect to localhost on port 23
Checking the firewall is perfectly valid - Does the device have any sort of intrusion detection? It might see your constant connections as some sort of attack.

comment What is the maximum connections practically supported by a 2.4 GHz router?
Your routers/switches/APs are all going to be limited by their memory and CPU, as well as the backplane (amount of data able to flow through it at any given time). So even if you have the CPU power and the memory to keep X devices connected, if the backplane can't handle the traffic, it still doesn't matter. If you want enterprise capabilities, buy an enterprise level access point.

comment Windows DNS Change IPv4 vs IPv6
Are you using IPv6 at all? You want to change the DNS settings for the protocol suite you're using.

comment No access from PC1 to PC2 with anything except ping
All of that said, can you be a bit clearer about what does and doesn't work? Can you ping by hostname? or just IP? Can you connect via SMB by IP instead of hostname? What are the permissions on the share on the server? Can you install wireshark or windump and take a capture of a connection attempt from both sides?

comment No access from PC1 to PC2 with anything except ping
Ping means you have TCP connectivity in order to get an ICMP message across. You are trying to use SMB, which requires many more things to be functional in order to gain access. Furthermore, if you are using hostnames (I'm guessing that is what you mean, though that is not a qualified name), then there is even more at work (unless you are pinging by hostname, rather than IP - you really didn't specify). "Admin" also doesn't necessarily mean you should have privileges to anything on any other machine (such as anything else in the domain or workgroup).

comment Is it possible to use a cable modem on two different ISPs for the short term?
ISPs typically have some very specific settings for their networks. You can certainly go back and forth if you can remember these settings and change them between visits, but there isn't a way to automatically detect and change these settings. Cable modems are a dime a dozen these days, so you might be able to pick up a cheap/free one on craigslist or other local exchange site to use temporarily (and then keep as a backup).

comment No ping to local IP from specific local IP only
step 3 will give you invaluable information. It will tell you 1) is the ping request properly received on the other end and 2) if it is received, is the client properly responding to the request. This narrows down specifically where communication is breaking down. Since you're on a small network, it probably will be either the client or the router, this step will tell you which one. The update you added is insufficient as all it tells us is that the host sending the request does not get a reply, there is no indication as to why. Next time you do this, watch interfaces on both sides.

comment What happens if I select “Block” a user in Skype 6.21 on Windows?
Given that the protocol is closed-source, all anyone can tell you is how it acts based on observed behavior, and since you have already observed the behavior - what more are you actually looking for?

comment Packet Loss during Ping
"intermittent network issue" sums up a LOT of different possible problems. Considering the use of 172.16.x.x, is it safe to assume this is an on-network ping across a single switch? Or is there more to this topography? What type of routing our you using? Dynamic protocols can cause random loss if there are null routes or other routing pitfalls on the network. You need to be much more specific about the path you are trying to ping across.
