Anyone feel that the wireless signal on the T2010 is weak? It has the Intel 4965agn wireless. In tablet mode, the signal degrades even more. I have used other notebooks with Intel 3945abg and the signal is stronger. I have the wireless transmission set to maximum in the wireless settings. Anything else I can try to boost the signal? Also, is it possible to replace the Intel 4965agn wireless card with an updated model?
