Just another thread to explain I too am on Three UK and have tried everything to stop this router from dropping the 3g signal (goes 75%, 50% 25% then 0%) then disconnects for a few minutes and reconnects.

 

This happens at total random times and I have literally changed all settings to try and solve this issue. I can only now come to the conclusion that this is 100% an issue with your router and hope it can be fixed by a firmware update. I am willing to test any beta firmware you may have as I cannot afford to buy another router and need this to work from home.

 

Here are my logs from a recent disconnect:

I am willing to try and test anything at this point as it seems to have gotten worse recently and is almost impossible to use the internet this way!  I have read through so many threads and posts of users with a similar issue. Please post here if you have this issue too so something can finally be done about this. This wasn't a cheap router and was bought on recommendation on being top class.

 

Pleas help! Anyone!
