I decided to go for 3.5G mobile broadband internet to play some mmo games in my spare time and use my n900 to tether the connection

but im suffering from real bad latencies and bandwidth issues. my isp is etisalat and they say the problem is with my device -.-

the latencies are like 300ms during noon and around 1000ms during peak periods at night

any idea whats up? i have the latest PR 1.2 update.

anyone else having this issue with N900s? or is this an ISP issue?

Hi Tobias,

i would say there is a lot of sources for u problem^^
it could be your n900, laptop, isp, game
or somethink i have missed to think about

first i would check your connection
from the n900 to the isp
so use "traceroute" on your n900 x-terminal

open the x-terminal on your n900
and type "traceroute google.com"
u should see a list with alot of ms values in it.

the ms value is the latence to every ip that is posted there

so if the value goes to high after the n900 hops to your isp
u cant do anything about it and your isp have to fix it
but i dont think he will^^

if the first value is to big i would say
there may is a problem that could be relatet to your n900
but i would need more information to say somethink about that

if the latence is fine
i would check the tethering device
connection to the n900
u can use "traceroute" or
on a windows maschine only "trace"
to find out the latence the same way

if you dont know which values are good and which are bad u can post the ms values here and i will check it later but only the ms values not the ip plz

for more help it would be nice
to have some more information
about your isp, laptop(os) and game

greetings from germany

I'm also using 3.5G (which is, in fact, HSPA+ (HSDPA, HSUPA, if You filter out stupid marketing names), without such problems.

First of all, it's plain bullsh*t that it's device fault. Most likely, You just got bad ping due to route between Your device and MMO game server. Other choice is bad quality of service from Your operator.

Follow Hoga advices, to filter out possible cases.

Hi Tobias,

the first *** line means that the router from your isp dont allows/dont respond to this command -.-
for me it looks like you run in to a slow down advice
from your isp like Estel mention
caused by

a) high traffic in your network note
b) low singal caused by some frequency interferers
c) somethink i have missed to think about^^

i would email my isp to ask if the problem could be fixed.
somethink like:

i have some latence problems with your (data-plan/3G)
normaly my latence looks like this:
traceroute output

if the problem happens it looks like
(time/date you have trouble)
traceroute output

Because i need the normal latence for my work i would like to know if you could offer me a solution to get this problem fixed.

Warm greetings to you...

greetings from germany
Hoga

ps: just to check make a trace from your laptop at the time the problem happens so u can see the n900 is responding fine

to do that open "cmd" dos-box and type "trace google.com"
the first ip sould be your n900
responding in the same time that it takes without the problem^^

3.5G (or any cellular data connections) weren't built for low latency. 200-400ms sounds like a fair expectation for 3 or 3.5G. 4G and LTE or whatever they call it these days *may* have lower latency.

Speed does not always correlate with latency. You can have a 10mbps connection with high latency, or a 56k connection with low latency (like 20ms pings on average)
