Network Drop Outs

[DCaiger]

My Network connection keeps dropping, I am using the Hub 4 in Router mode and have 7x Google WiFi Access Points connected via Ethernet and NetGear 100/1000 switches.

I run simultaneous ping to 8.8.8.8 and to my Google WiFi Master Access Point, the 8.8.8.8 ping drops on a regular basis.  It seems to be between two virgin IP addresses  

crosh> tracepath 8.8.8.8
1?: [LOCALHOST] pmtu 1500
1: ***.***.**.*  16.668ms
1: ***.***.**.* 12.477ms
2: 10.112.32.89 26.125ms
3: winn-core-2a-ae55-650.network.virginmedia.net 30.151ms
4: no reply
5: eislou2-ic-4-ae0-0.network.virginmedia.net 24.453ms

Get exactly the same when I ping from a Windows Laptop too

Any ideas?

tracepath not that useful run by wire

ping -n 200 194.168.4.100

If you were loosing DNS lookups against Google DNS that would be a concern.   

Pinging 8.8.8.8 is of limited use, Google DNS is a service provided by dozens of global servers, we do not know if they are all configured to respond to redundant ping traffic and repeatedly the results suggest maybe not all do respond.

I have tried the above

Tracing route to cache1.service.virginmedia.net [194.168.4.100]

over a maximum of 30 hops:

  1    17 ms    15 ms    12 ms  ***.***.**.*

  2    38 ms    30 ms    31 ms  10.112.32.89

  3    68 ms    30 ms    82 ms  winn-core-2a-ae55-650.network.virginmedia.net [62.253.122.77]

  4    21 ms    25 ms    23 ms  cache1.service.virginmedia.net [194.168.4.100]

Trace complete.

And also

Tracing route to 62.254.59.130 over a maximum of 30 hops

  1    17 ms    20 ms    14 ms  ***.***.**.*

  2    58 ms    72 ms    77 ms  10.112.32.89

  3    23 ms    23 ms    27 ms  62.253.122.101

  4     *        *        *     Request timed out.

  5     *        *        *     Request timed out.

  6    33 ms    63 ms    35 ms  62.254.59.130

Trace complete

Has dropped out numerous times today too

Again that is a DNS server what are the results from :   nslookup hp.com 194.168.4.100
Test how many times does the VM DNS not respond to lookups ?

Test the quality of the connection with the proper tools like :

https://speed.cloudflare.com/

https://www.samknows.com/realspeed/    
Once the test begins click on Run full test to see packet loss / latancy / jitter / upstream rate.

Samknows doesn't run, I'll look into that

Here is the cloudflare, though will run from a Windows laptop tomorrow as will get different result / speeds

Hi @DCaiger 

Welcome to the community forums 

Sorry to hear you're having issues with your connections at this time. 

I have checked the systems at our side and cannot see any issues that might be causing this. Your hub levels all look good and there is nothing in the area to suggest an area fault. 

I have checked your BQM and it is showing a full red graph, please double check that the IP you have on the BQM still matches with your current IP. There are no service issues at our side to suggest a total loss of service, unless you've had the router itself offline for the day. 

[legacy1]

ping -n 200 194.168.4.100 

and enable ping on your router for BQM

and use hub in modem mode and get your own router with 1Gb ports
