Laptop's Not connect back to Hub when rebooted

jvoce

Hi,

The issue is that started about 3 weeks ago.  Reboot my laptop then wont connect back to the hub, this is connected via ethernet cable, the same goes for my other 2 laptops, they are connected by Wi-Fi, reboot them and they wont connect back to Wi-Fi.  The only way to get them to connect is to switch the hub on and off.  Then they all connect ok.  I have had 2 engineers out, as power levels were down and i had a new hub replaced.  But still the same issue, any ideas?

 

cheers

Have the Hub signal levels been corrected to the point where the current Hub starts up and gets to a normal connected state ?

Hub Signal Level Checks


Via http://192.168.0.1/ connect to the Hub in Router mode, do not login in, scroll down to "Check router status"     Use http://192.168.100.1/ for a Hub in Modem mode

Using the Hub's "Check router status" tabs check the Downstream and Upstream power levels are in spec.

Downstream Power Levels of -7 to +7 dBmV are preferred, +10dBmV is the max acceptable, with a SNR of 33dB or higher across all DOCSIS 3.0 channels. Rising error counts across many channels is a current service noise fault.

Upstream
Power Levels of 35 to 49 dBmV are preferred, with QAM 64 Modulation mode across all four to six DOCSIS 3.0 channels.  Seeing QAM 32/16 or QPSK is a current service noise fault.

2 Hubs and 3 laptop's that all fail to work well with either Hub.

But  no mentions of any other connectivity issues with TVs / mobiles / Kindles etc.

What happened 3 weeks ago to all the laptops as they appear to be the items having the problems ?

New security software or VPNs installed etc ... ?

Tv's are ok, mobiles sometimes times out connected to wi-fi, quicker sometimes to switch it off on the phone and go 4g, only change to the hub is cctv added.  But unplugged this from the hub and same issue.  No software updates, just usual windows updates

got one laptop connected to the hub, but giving message "No internet, secured"  other is connected ok

"No internet, secured"

This is what happens when Wi-Fi Pausing / MAC Filtering has been used on any Hub.

This can also happen on a Hub 5 if the Hub's DHCP server fails.

Hi, no probs, had to reboot, still no connectivity to wifi, have to restart router to connect

Hi jvoce, 

Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums.

We're sorry to hear you're having issues with connecting to the hub. As mentioned by Client62, it sounds as though the WiFi is being paused. Please can to perform a full pin hole reset on the hub. You can do this by holding the reset button in for a timed 40 seconds. Leave the hub reboot itself and this should clear any pauses. 

Keep us posted on how you get on. 

Thanks,

Hi,

 

its a brand new router, surely shouldn't be doing this already?

 

cheers
