Hello everyone! I'm station in Germany and I sling my cable from Florida using a Slingbox Solo. The upload speed in Florida is 2Mbps. My download speed in Germany is 6Mbps. I'm using TCP on port 433 for the Slingbox. I'm able to get close to 1000kbps on best. When I switch to UDP on the router in Florida I can get 2000kbps. What do I need to do in order to get the best upload speed? I'm using a Belkin router in Florida and a D-Link router here in Germany. Any help would be great!
P.S. I also have Slingcatcher and the kbps is also the same speed.

I'm curious, how do you switch a router to UDP to double the speed? I guess Slingcatcher doesn't work in that case, right?
With UDP, you already get the max possible speed. To get the best speed (2000 kbps) with TCP, you need to check if the latency between FL and Germany isn't too big (I'd say anything above 150-170 ms means slow Slingbox speed). Or you can also try Slingbox Pro HD, that one tends to perform better than Solo when streaming overseas with higher pings. Also, tweaking MTU size on the routers can have positive impact on speed but I really can't tell you the optimal values, that's up to you to try. Just be careful, if you go too low (like below 1450) on the MTU size, you might lose connectivity completely.

I have my router in the States setup for remote configure. I can switch my port fowarding from TCP or UDP or both. Can you pleaes post instructions on how to check the latency? Also I checked my router in the States and it doesn't have any opition to adjust the MTU size.

Switching port forwarding to UDP is like if there was no port forwarding set up at all. Slingbox then falls back to SNATT connection, which probably in fact is an UDP connection but the problem there is that Slingcatcher won't handle it so I doubt you were able to get 2000 kbps in Slingcatcher like that.
To check the latency, simply use ping.

In my router configuration I have the option in virtual server to setup port forwarding as TCP, UDP, or both. I was getting 2000kbps using UDP on my laptop here in Germany. I did a ping test from here to my Slingbox and this is what I got.

Just an update. Once again tonight I changed my router in the States to forward port 5001 using UDP only. Here in Germany on auto I can get around 2000kbps using my laptop. Of course my Slingcatcher won't work, because it isn't compatible with UDP packets. Is their anyway to get that kind of speed using TCP? When using TCP I range between 600 – 1300 kbps using the Slingcatcher.
Thanks,
Joseph

You have couple of options:
1. Get Slingbox Pro HD, you should see improved speed over TCP. 168ms should get you speed of approx. 2300 kbps via TCP.
2. Try changing MTU. If your router doesn't allow this, get another one.
3. Use a proxy server, preferably from Trusted Proxies. This, of course, won't help for Slingcatcher and other devices that don't support proxies.

My question now is the Slingbox Pro HD says to have an upload speed of 1.5Mbps. I have 2Mbps, but of course the speeds isn't always 2Mbps. Should I still be okay?

The Pro HD will reduce the resolution if the speeds are not high enough. I prefer to have about 2.5Mbps for best HD quality.

What I don't understand is I have a 2Mbps upload in Florida, but here in Germany on my slingcatcher I'm only getting 700kbps. I have the port fowarded in the States and I also have it fowarded on my router in Germany to go straight to the slingcatcher. I'm so confussed and I don't want to spend the extra money on a slingbox HD and have the same exact issues.

With 168ms pings, you should definitely get the full speed. In your case, with 2 mbps upload, that would be some 1800 kbps max. With Slingbox Pro HD, you have much better chance to get such speed than with a Solo. But there are no guarantees. Slingbox streams are very sensitive to network quality.
You will never get a decent HD stream from a Slingbox without at least 3 Mbps stream. Even at 2500 kbps, Slingbox will drop a lot of frames, although the picture will look nice. All I'm saying is just that from my experience, Slingbox Pro HD delivers better speed than Solo.
