Problema com up dates do Eclipse 3.4

Boa tarde a todos

Estou com problemas ao fazer o up date de softwares (plugins) para o Eclilpse, sempre que tento fazer a instalação de algum complemento sempre dá algum erro, e o pior de tudo vocês até vão rir: em casa na minha simples banda discada tudo flui normalmente, consigo fazer a instalação obviamente que muito mais demorado, mas vai, agora na banda larga aqui na empresa sempre dá algum erro conforme descreve o log abaixo:

Se alguém tiver informações sobre esses erros de dowloads me avisem, até posso acreditar que seja alguma limitação da ADSL imposta pela Brasil Telecom.

Grande abraço!

Amigo não tenho certeza mas lhe recomendo verificar limitações de firewall e banda em sua empresa, ou quem sabe a utilização de proxy eu consigo normalmente usando banda larga
