Daily call Failed. Service unavailable

**ccalabro** · 13-09-2005, 11:52 AM

Hi, my tivo has been working perfectly for ages but suddenly the daily call is failing. The network is ok and i can connect to the tivo so i assume it isn't an internet issue. My friend tried a daily call and his worked fine.

Can someone please suggest what problem solving i can do to correct this?

thanks for any assistance.

Has it happened once, or many times?

Does it happen every time it tries or just randomly?

Are you doing heavy uploading/downloading at the same time?

Do you have another TiVo (or connected another TiVo) with the same type of network card and therefore you may have a MAC address conflict issue?

Are you runnning any different firewall software and/or settings since the problem started?

The most important bit is to check your TiVo can still contact minnie and is able to download files from her.

Try using the NetworkingHowto and scroll down to 'Configuration and Diagnostics' and work your way through the tests there. If you get stuck at one let us know and can try to help further.

i notice the mtu size is 1500 whereas with my adsl service i had to change my router to 1492 to get it to work. i have not changed any network settings on the tivo?

MTU isn't the issue, all TiVo's I've played with use 1500 and my ADSL uses 1492 same as yours.

Keep going down the list.

The most common thing to cause what you have, is your ISP inserting a transparent proxy into your service. Not all proxies will handle TiVo headers properly.

Anyway, we will find out as you go through the list.
