Overall the diagnostics look ok to me, only suggestion I'd make is to limit your connect speed to 41333 or 42667 to see if that reduces the number of Blers that you're getting.


Try using &U17&N28 or &U17&N27 in the Extra Settings for the modem.

In the 'Dial-Up Networking' folder, right click your ISP's DUN connection and select 'Properties', on the 'General' tab click the 'Configure' button, select the 'Connection' tab, click the 'Advanced' button and enter &U17&N28 in the 'Extra Settings' box there. Click OK on everything and then try a connection and then check the diagnostics to if the Blers, Link Timeouts and Naks have been reduced.

Agreed. If doing gaming, try S32=98 by itself in extra settings and see if it improves.

Im a gamer, I have given up on this modem, see the Gaming problems with 5610a modem thread.

I ordered a Zoom 2920 PCI Plus.

From Upset Chaps Gaming Connection Guide:
S32=98 (V34) - Disable all 56K connections
These strings will disable v90 and X2 connections and should completely stop retrains and speed shifts that cause phone jacks, albeit with a 32-42 ping increase. [quote]

Clearly this is not acceptable for gamers.. theres a big difference between a 280 ping and a 320 ping. USR users shouldnt have to resort to this to get a stable gaming connection. IT IS A SPECIFIC 3cp5610 ISSUE, that USR seems unwilling to adress.

Yea, I've said it before, I'll say it again...

Disabling V.90 isn't a good idea for gaming. It increases the amount of latency too much. For example, a V.90 connection usually yields a RTD of 100-110ms to your ISP's Access Server. A V.34 connection is much worse, with 135-156ms (or more) round trip delay to your first hop.

Bob's idea is a more intelligent solution. If capping your connection speed doesn't improve your ping spiking/packet loss ("lag"), then switching modulation to V.34 won't either.

Ok 2 more questions...with the Performance Pro came the "gaming mode" and in it the have the string " AT&FG" whats it do? ok Question #2 , I have a external 5686-01. Originaly it was a 5686-03 but I was having problems with it and sent it back and they sent me the 5686-02. I didn't think much of it at the time (looked the same,and worked ok)... so i kept it. Now with the V.92 upgrade is it worth the hassle of getting the 5686-03? Thanks again... and keep up the good work.

1. Gaming Mode basically just lowers your usual connection rate by 1-3 steps, and disables error correction and data compression. It actually helps quite a bit; in example, if you were playing Tribes 2, you would notice that if you were in a fight and you jumpjet from the ground, your proximity to the ground would be more similar to what you perceive client-side. Thus, responsiveness is improved.

2. I just purchased the 5686, and I'm happy with it. Happy as I can be with Modem, I should say. When I purchased the Modem, it ran the older "5686-03" Firmware you described. They have since updated it, however(5686-04), so I would suggest using Control Center to update it. If you have connection speed problems, try the string S34=32.

Oh yea, you can reproduce gaming mode by just lowering your normal connection speed by 1 step (e.g., normal connection yields 44,000bps, try 42,666), and turning off error correction & data compression. If you get alot of instability in regard to ping time, and significant packet loss, try 2 steps. You shouldn't have to go to 3 steps down, but you might try it anyway.

Well, I hope I've been of some assistance! Moo.


Hey Mikey, does your ISP support the X2 protocol? There's a local ISP here with Total Control boxes which I get a much better connection to using X2 instead of V.90. Moo once more.
