upload speed

MINANTRA

Hi everyone,
I switched to TalkTalk a few months back after a shocking and expensive 3 years with BT!
The ONLY problem I have with TalkTalk is with my upload speed, its 50% slower than it should be using my own router, either with an ethernet cable or wirelessly.
When using TalkTalks own router with my ethernet cable, I get a normal upload speed.
I am connected to the main socket and no extensions, I have tired different ethernet cables and micro filters etc.
I get 5MB download 24hrs a day, (line is configured for 6.5MB), and I get 150kbps upload with my router and 365kbps (line is configured for 480kbps) with TalkTalks router.

I obviously thought there was a problem with my own router, which has worked perfect for 2 years, so I went and bought a brand new router and the same thing happened, great download speed but 50% less on the upload speed!

Talktalk keep telling me its not their prob as the speeds coming into my flat are fine, so unless I purchase their own router for a wireless connection, they cant help!

Any experts who can help as I am confused!
Cheers.

Are the upstream rates the same on both talk talk and your own router?

That's really quite a strange one.

As you've said that you get higher upload speeds with your TalkTalk router, I would only imagine it's some strange configuration, like a weird MTU setting.

Many thx for replies so far.

I was also thinking about MTU, so I checked -
TalkTalk router (Huawei, SmartAX MT882)
Configured MTU = 1432
Actual MTU = 1400

My router (2Wire BT1800hg)
Forced Upstream MTU = 1500

Should I change my MTU to 1400 or 1432 to solve problem?

I have my MTU set at 1400 though i don't think that change will increase your upload speed as your only altering the size of the packet.... Try it though............

MINANTRA

YAY!!! I solved problem!!!!
I changed the MTU rate in my own router from 1500 to 1400 and now my speeds are perfect!
I just did a test at https://www.speedtest.net and my results were -
5.4MB DOWN and 388kbps UP!!!!!
Im very happy now
THX for everyones help.

Have you tried specifically changing the MTU on your Desktop using something like Dr. TCP?

I'd give that a go and play around with different configurations.

Brilliant!

Sorry for opening an old thread but I have the same issue - switched to talktalk becuase it was cheap but have really slow speeds and some pages get connection errors. Also have a BT1800HG router and keen to try the MTU fix .... but can't figure out how to do it. A google search brought me here so was hoping you could shed some light.

Appreciate any help
