I am new and a bit slow so please show mercy.
I have an all Apple environment (yes one of them) and am not very bright.
My Vodafone Station recently died and the kind people at Vodafone sent me a new Huawei HG659 for our adsl broadband as we are rural.
At home we have the HG659 at one end of the property connected by (LAN1) Ethernet cable to a 2015 iMac.
We then have another Ethernet cable (LAN2) connected to an Apple Time Machine Gen 2 at the other end of the house set to bridge mode as a wifi access point and router.
The Time Machine is then connected to a Mac Mini by Ethernet cable.
The time machine also connects to an Apple AirPort Extreme Gen 3 (also in bridge mode) in our shed via Ethernet cable.
The AirPort Extreme has a Western Digital 2TB powered hard disk which we store media, photos etc.
We have a bunch of airport expresses mostly connected via wifi to AirPlay music as well, one is via Ethernet cable to the AirPort Extreme in the shed.
As soon as I plug in LAN2 ie HG659 to the Time Machine everything turns to custard.
The ethernet to the iMac appears visible on network settings on the iMac but the machine can not browse the net.
The Airport Utlity keeps losing visibility of the Time Machine and shows the Ethernet as orange and the AirPort Extreme and the Airport Expresses connect and disconnect randomly.
The whole home network has ground to a halt.
I spoke to Vodafone (many times as this has been going on for a week or so and the polite tech said if they are getting Ethernet and wifi to their modem router they have met their contractual obligations to me. In other words...burn.
I have seen others have had this problem and am looking for the simplest option for a non tech person.
I can follow basic instructions if you speak slowly and provide pictures.
I realise I may need to buy a new modem router, happy to do that if that's the simplest solution but might need some help to find one that will work and configure.
I hope someone can help and thanks for taking the time to read.
Sorry if this is not in the right spot...
