I've just moved to a new apartment and with internet connection via a router and I'm finding that I can't connect to quite a few sites that use SSL.

For example trying to connect to PayPal:

curl -v https://paypal.com
* About to connect() to paypal.com port 443 (#0)
*   Trying 66.211.169.3... connected
* successfully set certificate verify locations:
*   CAfile: none
  CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* Unknown SSL protocol error in connection to paypal.com:443 
* Closing connection #0
curl: (35) Unknown SSL protocol error in connection to paypal.com:443 

curl -v -ssl https://paypal.com gives the same output.

For some sites it works:

curl -v https://www.google.com
* About to connect() to www.google.com port 443 (#0)
*   Trying 74.125.235.112... connected
* successfully set certificate verify locations:
*   CAfile: none
  CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* SSLv3, TLS handshake, Server hello (2):
* SSLv3, TLS handshake, CERT (11):
* SSLv3, TLS handshake, Server key exchange (12):
* SSLv3, TLS handshake, Server finished (14):
* SSLv3, TLS handshake, Client key exchange (16):
* SSLv3, TLS change cipher, Client hello (1):
* SSLv3, TLS handshake, Finished (20):
* SSLv3, TLS change cipher, Client hello (1):
* SSLv3, TLS handshake, Finished (20):
* SSL connection using ECDHE-RSA-RC4-SHA
* Server certificate:
*    subject: C=US; ST=California; L=Mountain View; O=Google Inc; CN=www.google.com

*    common name: www.google.com (matched)
*    issuer: C=ZA; O=Thawte Consulting (Pty) Ltd.; CN=Thawte SGC CA
*    SSL certificate verify ok.

I'm using Ubuntu 12.04, with Windows 7 installed as well. These sites work on Windows :(

Not sure if this information helps but I ran ifconfig and got the following:
