comment Ignore and override ISP router
You usually can't just plug in any old ADSL2+ modem into a DSL line and expect it to work. There are specific values necessary to negotiate with the DSLAM at the other end, specifically the VPI and VCI settings. There is a list of common ISP ones (speedguide.net/articles/…), but for the lesser known ISPs you'll have to call and ask them for their settings. If you're lucky, you can access the values read-only without a password in the current modem (though not all modem models allow this).

comment Packet Loss/High Ping with One Computer Seems to Affect Entire Network
ping timeout does not always mean packet loss. Capture from the other side to validate whether or not that device is actually sending the ICMP replies. It may be that the device is too busy at the time to pay attention to pings. The loss seen may be induced by a heavy increase in traffic caused by the PC you are adding. As noted by Joe, this is often the result of malware. A capture on the router will tell you how much/what sort of traffic of it is hitting the router from that PC. If the router can't capture, you can use an appliance: en.wikipedia.org/wiki/Packet_capture_appliance

comment What kind of IP address is this? (WIN-F9PTTKUMI2U:29901)
To be more specific, it isn't simply an address, it is a socket. The first part is a host name or address specifying which allows routing to the specific device, the second part is the port number which allows routing to the specific listening application.

comment Regarding the limitaions of “Listen Server”
A "ping" is actually a measure of latency between two points. What the ping application reports is round trip time in milliseconds using a protocol called ICMP (or sometimes UDP). If your friend hosts, then the round trip time, or "ping", to his machine will be however long it takes a packet to leave your machine, route to his machine and then for a reply packet to return back to your machine. Note that this value will be unique to your connection - anyone else will have their own unique route to his server and the corresponding round trip time.

Maybe its hidden? I found this relating to that file: symantec.com/security_response/…

comment Upgrade options for Lenovo 3000 C100 laptop
Looks like max is 2GB: crucial.com/usa/en/compatible-upgrade-for//…. And as for SSD, yes, but that doesn't mean you should.The interface type looks like it is an ultra ATA for the hard drive and an SSD with that interface is going to be much more expensive, here is a 128GB one: newegg.com/Product/…-2‌​0-208-894--Product

comment Is it possible to get a router's public IP address from wireless access points without knowing the keys?
@AthomSfere, the modem I use right now is bridged - most of the modems I have ever used across 3 different states and 8 ISPs, both cable and DSL, were also bridged - it isn't niche, it is a standard practice for many ISPs. The ISP I used to work for used bridged modems for all consumer line products. The business line products (SDSL,IDSL,T1) had routers. Even the EoC bundled service had a bridged connection.

comment What are the requirements for a “Listen Server” in video games?
Yes, latency is measured by round trip time, so that includes all legs of the journey between both end points.

comment Wired connection being dropped
If it does that repeatedly then it is a flapping iface. The link down indicates a break on layer 2 which usually is a physical issue - that can be cable, NIC or switch port. Try moving to a different switch port. If the issue continues, try replacing the cable. If that doesn't work, it is probably the NIC.

comment Wired connection being dropped
"device is not ready" may indicate an issue with the driver talking to the card - maybe a firmware issue on the card? still could be a driver issue as well.

comment example.com cannot be resolved to an IP Address
At the very least, dig output to the address would help us get started.

comment What are the requirements for a “Listen Server” in video games?
Bandwidth does matter, but so does the type of connection. For instance, T1 lines typically have lower latency than ADSL lines - and that has a lot to do with protocol, equipment and distance. Another reason is that T1 lines are symmetric whereas ADSL is asymmetric (that is what the A in ADSL stands for) - which means that you can get bottle-necked on either the upstream OR the downstream - just one of the directions being clogged will kill latency on the entire line. All communication over a network (or the internet) is two-way, so you need both sides to be clear.

comment Wired connection being dropped
that might be a NIC issue, or driver issue. I'd try updating drivers first - you don't have a lot of options on those if it is hardware issue. I've seen issues where a bad cable can have similar symptoms as well.

comment Difference between WAN IP & LAN IP
If you have a CIDR block, then it is a group of static IPs (look up CIDR on wikipedia for an explanation of what /29 translates out to). They are also public IPs and it is not required that you use them (you can NAT and just use the WAN IP if you desire. However, if you have servers, you can use the LAN IPs and use the gateway provided to route those through the WAN IP.

comment Difference between WAN IP & LAN IP
It looks like a routed block. You would set up the first block on the router's WAN, the second block could then be used in the LAN with a gateway on the first block. Not entirely sure - but the ISP I used to work for did things like that.

comment Why does the set command display more environment variables than the environment variables gui?
It is not uncommon on many operating systems to only include common config option in the GUI for standard users and expect that advanced users who would more likely need the less standard options will prefer the command line for their work.
