Legacy Network Woes

Then I would also after trying the 2nd nic but also check and see if you can use another port on the router mate just in case it has gone faulty as well. That way if the 2nd nic doesn't fix the issue go back to the 1st nic and try the router see if you can use another port and if that fixes it go back to your nic teaming again

looking like its the router - bt sending an engineer out on monday - if its an issue our side we are being stung for ?235 but free if it is the router etc

[Aaron]

Honestly it seems like you've basically covered everything so I wouldn't even think about it I would just be it's an issue with the router

[Gerard]

Router Replaced with new business hub 5, seems like all problems are cured

[Aaron]

excellent good to hear

Try making your own router. We had to use this as we have to many concurrent users for a standard router to coupe with.

Tbh I prob should this is the 3rd modem we have went through this year, I'm beginning to think they can't cope with the requests. Though I was gonna pull the gateway from our dhcp server to limit what's sent to the router to only http from our censornet box to see if it makes much difference

[Gerard]

so my internet issues are still occurring, BT now saying the modems dropping out due to high usage which cant be the case as we are approx 50 devices down from last term when it was working perfect.  - they told me to wait another 72 hours and report back then they can look at the logs etc  and send ut an engineer if needs be.

connection has dropped 5 times today - all at times when classes are using it

May have to look at that pfsense

[Belfast_Tech]

Our's has also dropped at least 2 times today also.  The actual BT router automatically rebooted itself once too, but the other time it just ground to a halt temporarily.

From the logs it looks like TCP reset attack is being detected, but funnily enough only when most of our Macs (18 iMacs) get woken from sleep & get logged into at once.

Gerard just seeing this now, was off for a few days 


Have you upgraded your Censornet to the latest version as we had a similar problem here and the Censornet upgrade to version 5.2.65.2.6 seemed to sort it out 

[Gerard]

yup running 5.2.10 which was only upgraded last week and made no difference

[Gerard]

although its strange you had a similar issue and me and belfast_tech are having issues too and are all running censornet

[Telone]

Try disabling SSL/HTTPS inspection and see if that makes a difference found under Settings SSL .

[Gerard]

will try it sometime today , any idea when i enable it again will the same certificate apply or does it generate a new on?

[Aaron]

same certificate should still apply Gerard.

I would also look at do you use Sophos? it has a setting which checks every single webpage before allowing a user access to the page to make sure its on a safe list but this also means ALLOT of internet activity between yourselves and Sophos which could put allot of strain on the router depending on the amount of users accessing the net. You can switch that off within Sophos and see if that does improve
