Problem :( Pls help!

Okay the other day my phone line went down and I called the phone line company to come and fix it - and they did, they sent a technician today. Apparently the lines to my house were brittle and broke at the router box for my area. Therefore they had to install new wires for my line. Now here is the interesting thing; while my phone was down (all of yesterday) I was able to still use my internet (I have Bell Sympatico DSL). When i conducted a speed test i noticed that the download speed was relatively slow, yet the upload remained unaffected. There was difference in upload even though my phone line was down.
Well now that my phone line is back up and working again, I conducted a speed test and my speeds are slower than before, but my upload remains the same as before, wasn't affected at all! wth?
Is there anyway that the new line affected my DSL download speeds? I'm posting here before I decide to call Bell tech support to see if anyone has any ideas.
Maybe i should try tweaking. My caps are 3000/800 and I;m using Win XP Pro. Here are my analyzer results:
TCP options string = 020405ac01010402
MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.
Default Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 120 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000
