Host Networking w/ Shared Internet performance SLOOOOOOOW

So, thanks to this forum I figured out how to connect from a T-Mobile Hotspot, by using Host-only Networking w/ Shared Internet. However, the network performance from my XP VM is insufficient for any real use. At least that is what I believe the problem is. Webpages take a long time to load, and often time out. I can't run Windows Update at all. Meanwhile, the performance from the OS X side is just fine, so it's not the external network.

Any suggestions on what I can tweak to improve the performace for the XP VM? I have checked and there are no errors being generated in my console or ipfw logs.

Thanks!
 
Almost sounds like DNS problems. At least that is where I'd start. I'd be curious to know what the setup looks. Host IP's, netmasks, default router addresses, hops to router, DNS addresses, etc. Is NATing going on? And if so, are you forwarding the MAC address of the guest?

Hi,

I have the same problem with parallels in Mac Osx (on an intel machine)


The dns isnt any problem, it just looks like i cant download more than a few kbyte (in the browser, in windows explorer and even when i try to log on into a domain)
check wget
Code: 
C:\Documents and Settings\Kipz0r>wget ftp://ftp.xs4all.nl/pub/test/10mb.bin
--13:46:24--  ftp://ftp.xs4all.nl/pub/test/10mb.bin                                 
=> `10mb.bin'

as you can see the resolving isnt any problem.
I have more problems with looking at websites with a bit more content than usual (google eg. works, the wget homepage doesnt)
Ping is also kinda odd (ping -l 1472 www.google.com):

Code: 
Pinging www.l.google.com [66.249.93.104] with 1472 bytes of data:
Reply from 66.249.93.104: bytes=56 (sent 1472) time=10ms TTL=246
and ping -l 1473 www.google.com:

Code: 
Pinging www.l.google.com [66.249.93.104] with 1473 bytes of data:
Request timed out.


and finally: my ipconfig all

Code:

Wow

well, if you are a retard with this then i am really in trouble! ;-)

so, i read thru your links (thanks!) but have one question. i have 3 adapters listed in the interfaces section of my registry. none have an MTV parameter, so i will add that, but how do i know which adapter to edit?
 
ok,

at first: hurray for retards! \o/ :P


I neither had a MTU setting in my network cards. But if you take a look at the different network cards, you'll see also an ipadress.
Thats the way i found out wich card i had to pick.

then make a new D-word value and change the value data to 1000(decimal) or 3e8 (hex)

you can fiddle around with the mtu, but, as it is my computer at my work, i don't. Yet.
(havent got time, have to read bash.org etc.) ;)

Hope that works for you as well.


Cheers.
 
Set the MTU all the way down to 900 and no improvement. Hmmm, anything else to recommend I check?
