Hello @Mkalantari87,
welcome to our o2 Community 
I am sorry that you are having trouble with your new homespot. Some questions:
Are the WLAN and LTE/5G lights on permanently (green) or do they go out sometimes?
There may also be disruptions in the mobile network at your address at the moment. You can check it here: Live Check. This could affect the network reception with your Homespot as well.
Please let us know if you have any further questions.
Best regards
Giulia
Thanks for the answer. The light is green most of the times. The problem is not about the network connection of the home spot. The problem is that each time I am disconnected from the home spot, my phone doesn’t connect again automatically when I come in the range of that. I have to turn the wireless of the phone off and again on and then it connects to the spot. There is a kind of problem with the home spot. The O2 shop has checked and confirmed the need for changing the device but I don’t know why after 12 days they didn’t send it to me.
Dear @Mkalantari87 ,
I have just taken a look at your case.
You don't have a Homespot for rent with us, but a purchased one with instalment payments. We can't simply exchange it.
This probably also explains why the exchange order was simply not completed and not sent. 
You can send in the purchased router like a defective mobile phone in our returns portal, then we will check whether it is defective and if it is defect, you will receive a new one.
Kind regards,
Andrea
Dear Andrea
thanks a lot for the nice information that you have figured out for me. Actually I didn’t select to buy the device from O2 or to rent it. I even didn’t know that it is possible to rent the device too. The O2 shop said I have to pay extra for the device. Now I see this became a problem! If I have rented that, then was better? So please teach these things to your agents in O2 shops. I am really tried with following up each week two times in the shop and get no right solution. I had the problem since I got this new device and the contract. Now as I am sending this message still I have the problem:(
I will try to find a way to get out of this contract
Dear @Mkalantari87 ,
the Homespot 5G you owe is a new model and ist is only available as buying version, the ones for rent don’t support 5G and are older models. Thes cost 5,99 and 4,99 euros a month as long as you use them. The advantage of the rental version is that you get a new one if the old one seems defective and then send the old one back. If you buy your own, it has to be sent in for repair and you don't have a router for that long.
However, since you bought the Homespot in the shop, you cannot cancel the purchase. The best thing to do is to go to the shop and ask there.
Kind regards,
Andrea
Thank you Andrea for the detailed declaration and kind following up the issue. I was yesterday in the shop and they will send it to the repair center. At the meantime had to buy a small LTE sim router, it works with out problem and is a proof that the big 5G guy was not working right. Hope they can solve it.
Hello @Mkalantari87,
thank you for your kind feedback
Please let us know if you have any further questions.

Your welcome, thanks for the declaration, I will try to inform you on the results and hope the problem will be solved soon
Happy new year @Mkalantari87! 
Has the router already arrived repaired with you?
Is everything working like expected?
Greetings,
Katja 
Hi Katja, thanks for the following up, yes it has arrived, actually I have got a new one. I turned the 2.4 and 5 GHz Wlans. Off and then connected the spot to a simple router (the cheapest only router in the market from TP link) and then with the cheapest TP link extender made a Mesh in the house. It is now perfect.
I suggest to everyone who wants to use the O2 homespot and also to enjoy the mesh technology, to do so.
thanks again
Hey @Mkalantari87,
thank you for your kind words Have fun with your homespot!
Greetings,
Flo
