Question "ERR_CONNECTION_CLOSED" on various sites and I don't know why ?

[TheExperiment01]

So sites like https://www.fnb-online.com/ and https://www.ea.com (specifically when I click login for ea). I've tried everything I can think at this point, different browsers don't work (other devices on the network work), firewall turned off, updating drivers, clearing cache, using google dns and probably more things I cant think of right now. I really need some help here. I've also gotten RESULT_CODE_HUNG for sites like intel.com and https://aegide.github.io/ (specifically whenever I input anything for the latter). And for some additional info I tried pinging https://www.fnb-online.com/ and sent 4 packets and received 0

ISP: connection DSL, coax, fiber?

Make and model information for modem and router? (Or modem/router if combined.)

The router's logs (if available and enabled) may provide some clue.

Who has full admin rights to the network router? You will need help from that person.

It is an xfinity Arris tg1682g with dsl connection and it’s my home network and I don’t believe it has logs enabled

This router?

https://secure.xfinity.com/anon.com...220_Wireless_Gateway_3_UserGuide_06_19_15.pdf

Manual appears old....

Did not note any references to the availability of logs and/or enabling such logs.

However, the only way to know for sure what is available within the router's admin pages is to log in and search.

Just do not change immediately change anything.

On your computer run "ipconfig /all" (without quotes) via the command prompt.

Also run "arp -a.

Post the results. You should be able to copy and paste the results without needing to retype everything.

Displays and modifies the IP-to-Physical address translation tables used by
address resolution protocol (ARP).

ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr] [-v]

-a Displays current ARP entries by interrogating the current
protocol data. If inet_addr is specified, the IP and Physical
addresses for only the specified computer are displayed. If
more than one network interface uses ARP, entries for each ARP
table are displayed.
-g Same as -a.
-v Displays current ARP entries in verbose mode. All invalid
entries and entries on the loop-back interface will be shown.
inet_addr Specifies an internet address.
-N if_addr Displays the ARP entries for the network interface specified
by if_addr.
-d Deletes the host specified by inet_addr. inet_addr may be
wildcarded with * to delete all hosts.
-s Adds the host and associates the Internet address inet_addr
with the Physical address eth_addr. The Physical address is
given as 6 hexadecimal bytes separated by hyphens. The entry
is permanent.
eth_addr Specifies a physical address.
if_addr If present, this specifies the Internet address of the
interface whose address translation table should be modified.
If not present, the first applicable interface will be used.
Example:

arp -s 157.55.85.212 00-aa-00-62-c6-09 .... Adds a static entry.
arp -a .... Displays the arp table.

 

[Ralston18]

Just run "arp -a" (without quotes) and with a space between arp and -a.

However not seeing anything astray via "ipconfig /all" relevent to the described problems in your original post.

Any other websites that do not work?

Post a list accordingy.
