SH3 wifi connection ok but no internet. Ethernet intermittent

Hi all

having an issue with my broadband. SH3

it started a couple of days ago when I couldn’t connect to wifi. But could connect to Ethernet and had internet via eth. Then I could connect to wifi but couldn’t connect to 192.168.0.1 but could on Ethernet. Then I lost internet on eth and wifi but could still connect to 192.168.0.1 on eth. This has been random with different parts working randomly. Sometimes I have wifi with internet sometimes without. Majority of the time I have internet over eth 

 have tried factory resetting the router. The wifi worked for 2 mins then dropped. I have tried changing my wifi channels to channels with no other users.  I have also turned off wifi optimisation and split the 2/5g said with different names. Once I did this wifi worked for about 10 mins to the point of me changing the networks on all my devices then it dropped. Sky q is bouncing between connected to router and internet to only router to nothing.  i have tried removing the 3db attenuator and this helped slightly for a short while but put my power around db then started cutting out again. so attenuator is back inline.

there are no recorded faults in my area. The network test on 192.168.0.1 doesn’t find anything wrong and vm support couldn’t find an issue and told me to monitor for 48 hours.  Apart from going and buying a new router and putting the sh3 into modem mode I’m at a loss. there was numerous t3 timeouts before i split the ssid however these aren't in the log following a restart and now i just have rcs partial service and no ranging response received.

Any help or suggestions will be greatly appreciated.

Re: SH3 wifi connection ok but no internet. Ethernet intermittent

Your Upstream power level is just on the limit of 51.  The rest look okay. The SYNC errors in the log is not so good though.

However your wifi environment is a nightmare!  You obviously have loads of competing signals and it's no wonder your wifi is flaky. It may improve if you bought your own wifi kit, perhaps Unifi Access points or similar.  Or a decent Mesh system?  I'm just guessing the Hub 3 is being swamped and it can't cope.

You have said your cabled connections are fine, so that sort of proves the issues are with the environment.

As VM do not guarantee any wifi performance, it looks like it's up to you to sort it out really.

Re: SH3 wifi connection ok but no internet. Ethernet intermittent

Cheers.

strange for it to affect Ethernet intermittently though but that could be unrelated.

Yeh I have been looking for a better router. So may end up going down that route. I suspect it’s the tp link living room that a neighbour has that is interfering as it seems worse when that is visible. So they may have just got that in the past few days or so. My sh is about 6 years old so thought it could be that wearing out but some people have had them for years longer and they are ok. As I say I will see if it improves and if not will buy a new router. 

have been thinking maybe the tp-link archer a7 or c7 ac1750.

Re: SH3 wifi connection ok but no internet. Ethernet intermittent

Personally in your crowded WiFi environment I would look at the possibility of a Mesh system with the units running a cabled backhaul. That way there will be zero WiFi interference between the satellite units and the “main” one. Or perhaps a couple of PoE Unifi Access Points. These may be a hassle to install but would be worth it IMHO.

Re: SH3 wifi connection ok but no internet. Ethernet intermittent

Tbh I already have Ethernet running through the house I only need wifi in the office bedroom and living room so access points with eth backhaul shouldn’t be an issue. 

thanks
