Unable to upload and download at the same fourth dimension

I am a FP client and have an unresolved issue that has gone on for 2+ years at present.

The effect is that I cannot upload and download at the aforementioned time. My service is 768kb/s upload and 7Mb/s download. I accept the router upload speed throttled at 600 kb/south simply when doing an upload, my download speed to close to naught, making service unusable.

I spent a solid ix months with FP staff, who were unable to aid. A friend of mine thinks information technology is a duplex issue. Everything was fine up until two years ago.

Attached is a recent speed test when doing a file upload. I have screen shots going back to 2012 but FP is unable to assist me or does not know what to do. I would leave FP but take no other options.

Welcome to BBR

Asymmetric speed causes bug if upload saturates the aqueduct. TCP/IP is uses a handshake so while downloading ACKs are traveling in the other management letting the transmitter know all is well. If ACKs are delayed the transmitter thinks at that place is a problem and stops, or delays packet transmission.

If Ping/Download/Upload are normal when nada else is using the Internet the trouble is within your network. Some router'south are able to prioritize ACKs or implement QoS levels. Depending on what yous are uploading it may be possible to throttle it so it does non saturate the upload channel.

I do have the upload throttled at 600 kb/s, but does not assistance with download speed crashing to naught. Non upwardly to speed on QoS configurations.

I could see the download coming down a little, merely not like the event above.

Would the same happen if I moved to a cable broadband? Or as yous said, something specific to the router, although have used diverse routers over the years and have never had to mess with QoS.

I could run into the download coming down a little, but not like the result above

It tends to be pretty dramatic in one case ACKs go delayed too much.

Try reducing the throttle value until the trouble goes away. That is pretty inexact setting. Hopefully y'all can observe a happy compromise.

Upstream saturation is e'er an issue due to the way TCP/IP works. Highly disproportionate speeds exacerbate the problem due to the mismatch in channel speed. If the ratio of upload to download is better in cable the phenomena will exist less pronounced.

I suspect you are specifically having problems with the bundle queuing on the outbound interface. I'm not sure how configurable your router is but in that location may be some knobs you tin can tune.

Are you running multiple concurrent transfers at in one case? That will certainly cause problems by filling the queue and not assuasive the ACKs to go through, which causes your download to slow.

Also, you might try asking for a new router. Its possible a new router will have dissimilar queueing behavior.

Don't you lot wish? This is what all FP connections should be.

Someone already stated it, but every bit mentioned, when uploading at the aforementioned fourth dimension as downloading, especially if the upward line is maxed or close, it volition driblet the download speed significantly or cut it down to cypher completely. It happens with my 33Mbps/6Mbps connection. As long as I throttle the upload to about 745KB/s, then the download will max out. However, if I let the upload max out while downloading, my download speed will exist very ho-hum and altered.

Sweet latency on the upside. Perfect for gaming. Satellite might beat you. I would drop the upload to nearly 384Kbps unless yous are uploading a file.

I besides had this issue when I had FP DSL Package: 7.1Mbps/1Mbps. Equally I said, scale dorsum the upload fifty-fifty further. Also, you could have a worn/trojan. There was another computer hooked upward to the LAN and the download speed was abysmal, and so was the upload. Come to observe out, the exploit was using the computer as a zombie spam server so I formatted information technology and low and behold the issue went away. Probably non the result.

One more than affair. Before FP took them over information technology was (cough) Pivot.Internet. I had the whopping 265Kbps/96Kbps package which I upgraded to 768Kbps/384Kbps. Anyways, the download was completely dependent on the the upload. They used the first, original DSL which I believe is G.Lite (correct me if I'm wrong). As the upload increased the download would decrease. If I was downloading something, I would take to cap the upload to 0Kbps in club to attain full download speeds. This had nil to do with the exploit server. It was a weird quirk. I just thought I would throw that in at that place. Also, FP is somewhat forgiving. I cannot believe it either, but dispute your speed and *contend*, and they will more and so likely give you at least a month free. My connexion dropped for 3 weeks and I had two techs and a supervisor at my business firm trying to effigy it out. After 4 hours they claimed it was a hop in New York that was dumping my connectedness. I then received four months of complimentary internet. Arguing works better at an office because they don't desire a scene. Deplorable.

Forgot to say, again as the above affiche mentioned, information technology is more than then likely the modem. Something is wrong with the outbound packets which has a direct issue on inbound traffic. It shouldn't exist doing that. Also scale the speed back in increments of 16Kbps.
