Running slow on 4G with the Evo #826

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Which device (manufacturer, type)? Evo 4G

Which firmware is installed? 2.2 / Baseband version: 2.15.00.11.19 / Build 
number: 3.70.651.1

What version of wireless tether are you using? 2.0.6

What steps will reproduce the problem?
1. Running Wifi-tether with the Sprint 4G network connected.

What is the expected output? What do you see instead?

My phone's connection is about 4 Mbps, but when my iPad is tethered it only 
runs at about 0.5 Mbps. 

Please provide any additional information below.

The iPad connects at about 6 Mbps when connected to my home wifi network. 

I haven't tried connecting the Evo's wifi tethering to anything except the iPad.

I'm wondering if Wifi-tether is only transmitting my 3g connection instead of 
my 4g connection. 0.5 Mbps is about how fast my 3g connection is.

Thanks for any help...

My problem is the same, except that I'm tethering a MacBook Pro to my HTC Evo 
4g on a 3g network.  I haven't done a speed test, but it's remarkably slow, so 
slow as to be barely functional.  If I try to load two tabs at once, they both 
fail.

Thanks in advance.

I went ahead and tested this on 3G. It looks like I'm losing about 1/8th of my 
available bandwidth. My 4G is running at 4 Mbps and tethering at 0.5 Mbps and 
my 3G is running at 0.4 Mbps and tethering at about 0.05 Mbps. 

I'm wondering if there is any settings I can modify that will improve things, 
or if this is just normal. I had a similar drop when tethering my Palm Pre via 
wifi. 

Either way, I wanted to thank the developers for their hard work on this app.

I'm having the same issue. Wifi tethered 4G gets perfect upload speeds (1 
Mbps), but download is capped around 150 Kbps. On the phone, download is around 
6 Mbps via the speedtest app. I also get full speed downloads via USB 
tethering. I'm running CM7 (tried 7.0.3.1 and 7.1.0 RC1). Wifi tethering used 
to be close to full 4G speed when I last used it about 7-8 months ago (usually 
use USB tethering).

This may help pinpoint what's going on:

According to this thread, installing filterproxy and setting the tethered PC to 
use the phone as a proxy enables 4G speeds. There are a lot of people saying 
this worked for them, and indeed, it worked for me as well.

Hopefully this will help identify how to fix the underlying issue (or at least 
work around it).
