Toshiba laptop wireless networking erratic and slow

[Jim Byrnes]

I have a Toshiba Satellite C55t-A running an up to date Saucy.  I am 
having great difficulty connecting wirelessly to other machines on my 
home network or to the internet. After multiple tries I can usually 
connect but the connection is problematic and slow.  I don't think that 
my router is the problem.  My daughter has a lenovo thinkpad running 
12.04 and it connects with no problem. While she was here over the 
weekend I conducted some tests, pinging various machines in sets of 99 
pings.

Lenovo --> desktop  avg 1.76 ms with zero pkt loss
Toshiba --> desktop avg 86.30 ms with 10% pkt loss
Desktop --> Lenovo avg 12.85 ms with zero pkt loss
Desktop --> Toshiba avg 84.82 ms with 12% pkt loss

The results of lspci:

The 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. 
RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 07)

05:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE 
Wireless Network Adapter (rev 01)

The driver in use is rtl8188ee. Googling the driver didn't produce any 
useful info.  Software & Updates didn't show any additional drivers.

Hoping someone else is using this adapter and knows how to get better 
results.

Thanks,  Jim
