Have 13mbs down 12 up on 35/35 plan. Is that normal??

That doesn't sound too normal. What Operating System do you run? Have you tried rebooting your ONT and giving your router a Factory Reset?

Run the Fios Optimizer on Verizon's site.

Do you have an ONT in your unit or are you using VDSL connected to copper?

reply to bronxlcsw
Its the new ONT in the garage. How do i reset the ont??

run the optimizer. www2.verizon.net/help/fios_settings/optimizer

My 35/35 plan speed has dropped to the same speed as my previous 25/25 plan. I've reset the router, rebooted the ONT and no change. Verizon account shows I'm still subscribed to 35/35. Guess I'll have to give them a call and see if anything is going on.

reply to bronxlcsw
Are you testing on a wired or a wirless connection? If you are connected wirelessly, try a wired connection and post your results. A wireless connection may not attain your provisioned speed.

go here and paste your results.

I connected the ethernet wire and still get the same result only slightly faster like 14.5 down and 13 up. I suspected the installer, who decided to use existing home cable wiring, may have slowed me down. However, i connected the router directly to the ONT without any splitters. Still the same speed. Under the older DSL technology if you lived a certain distance from a central office you were pretty much doomed. does the same hold true for FIOS??

it's either your PC (that's where the optimizing would kick in) or they have you programmed for 15 or 20mb speed (your speed results make it look like that is not the case but you never know)

you can log in at www.myverizon.com and check your account summary and it will tell you what you are programmed for.

More Fiber- I am on 35/35 and getting almost 43 over 38. I have run the fios optimizer. Looking at these results is there anything that you would change to make my system even faster?

TCP options string = 020405ac0103030201010402

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 your MTU value.
Default TCP Receive Window (RWIN) = 66792
RWIN Scaling (RFC1323) = 2 bits (scale factor: 2^2=4)
Unscaled TCP Receive Window = 16698

In Windows 7, unless "TCP/IP Auto-Tuning" is disabled, only the Current TCP Window is displayed. Use the SG Vista TCP/IP patch instead of the TCP Optimizer for automatic tweaking.
RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65535 does not justify the header overhead of enabling TCP 1323 Options. You might want to use one of the recommended RWIN values below.

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
63888 (up to 2 Mbit lines, depending on latency. MSS * 44)
127776 (1-5 Mbit lines, depending on latency. MSS * 44 * 2)
255552 (2-14 Mbit lines, depending on latency. MSS * 44 * 2^2)
511104 (8-30 Mbit lines, depending on latency. MSS * 44 * 2^3)
1022208 (25-60 Mbit lines depending on latency. MSS * 44 * 2^4)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2672 kbps (334 KBytes/s) @ 200ms
