Wifi Rx speed too low - Tilt, TyTN II, MDA Vario III General

Dear all,
On TyTN II, I found something strange, either on WM6.0 and WM6.1.
When you go in Setting/Connexions/Wireless network, you can see some technical details, including Rx and Tx speed.
I have tested to improve performance in Power Setting tab, and even after a Restart of the TyTN II, no change on Rx speed : It remains at 1 Mb.
Performance is always :
Tx : 54 Mb
Rx : 1 Mb
Is there a way to increase the Rx speed ?
Thanks in advance.

Did you try on different access points?

Yes... At home (Freebox), at work (D-link access point).
Same results...
Any idea ?

I get the same behavior after the upgrade to WM 6.1. I believe it to be a display issue as it certainly doesn't seem any slower, but that could just be perception. Would need to run a connection benchmark to verify.

On a second look, I noticed that initially the Rx Rate tends to fluxuate between 54Mbps to 1Mbps before settling on 1Mbps. I'm still thinking its a display issue, but I'll do some ore testing today (I noticed the Rate doesn't seem to change with the signal quality).
Edit: I think I see what's going on. This probably has to deal with the power management on the phone. When the phone is idle (not receiving anything) the speed drops to 1Mbps after a period of idle time. If I ping the phone from my system, the Rx Rate immediately steps up to 54Mbps and stays there until some time after the last ping (when it drops back to 1Mbps).
So basically:
Idle (no data being received): 1Mbps
Active (data being received): 54Mbps (or whatever the best speed it can reach is).
Data receive finished: Sits at 54Mbps until a certain amount of idle time has passed, then returns to 1Mbps.

Idle (no data being received): 1Mbps
Active (data being received): 54Mbps (or whatever the best speed it can reach is).

Welll... You are right.
After some testing, when data are received, Rx rate change and go back to 1Mb when flow stops !
In fact, no problem... Just a value that is adjusted in realtime
Thank you very much for your help.

WiFi RX Rate Question - Help

Hi,
New to this forum and have a question. I recently notcied on my AT&T Tilt that the TX Rate is reported as 54Mbps but the RX Rate is reported as only 1Mbps. I thought it might be a problem due to configuration changes I had made so I reverted back to the original AT&T configuration.
I still can only get a RX Rate of 1Mbps. Now, in the AT&T configuration I see the RX Rate jump to 54 Mbps for a split second once and a while before reverting back to the 1Mbps.
Is there a way to get the RX Rate to operate at a higher bit rate?
Any help would be appreciated...
Thanks,
Dear,
I found the same config with my tytn ii, with original htc rom and all new roms tested.
Maybe this is a "standard" config.
BR,
Laurent
try changing your power save settings. Granted, you're going to drain your battery very fast by doing so but it is a solution. It's under Settings->Connections->Wireless LAN
did that it did not help
i also tried my router in fixed g and fixed b mode with no different results.
I have got the same problem.
I guess it's a problem of the driver since this function working well on original firmware.
My solution is turn off the wifi for few second and try again.
Sometimes, it may work.
But if u still get the problem, you should flash your device to original rom or others' ROM.
I thought this was a cosmetic issue and the actual RX speed is the same as the TX speed? I know if I check my Wireless AP it shows my Kaiser connected at 54Mbps but doesn't show separate RX & TX rates?
Could be wrong though?

Resco v7.03 & slow wifi drive access

as subject, i have speed problems with resco, it download files from my pc through wifi at max 39kb/sec.
Notice that a speed test with internet explorer, retrieve very good results. Has someone the same issue?
Same here
I have the same issue... it's unbearable to transfer a file over wifi from my home PC to the phone... a problem I didn't have with my old DELL Axim x50v or my Qtek 9100...
Haven't found a solution yet, please help!
try to upgrade to v 7.05 and set wifi power to BETTER peformances
Is your wifi set to best battery or best performance as this changes speed from 120kbps for me to 320kbps.
Also how good is your signal. The diamond has a very small and weak antenna, even right next to my router I dont get anywhere near full signal strength.
How much do you understand about wifi? Basically, the weaker the signal the slower it goes. To get the full 54mbps you need to be close and in clear line of sight. As the distance increases and the signal gets weaker it slows everything down to keep the data integrity and can eventually go as slow as 1mbps.
The best you can usually expect is 34mbps real world speed.
Also, for each drywall the signal is weakened by 25% and for each brick wall it goes down by 50%. So those who expect the range to be the 100meters written on the box are often left dissapointed. Generally it will cover your house and nothing more.
Also note thats 54mbps (Mega Bits Per Second). Most seem to think its megabytes.
Solved!
All right! Switching to BEST PERFORMANCE instead of BEST BATTERY improved the transfer speed over WiFi from 30Kb/s to 250 Kb/s!!!!
Thanks to everyone who replied!
my max is 520Kb/sec (peak of 5-6 sec) with a Belkin router + ddwrt firmware.

degrading Wi-Fi download speed

Hello,
I'm having an issue with my HTC one. When I make a fresh connection to my router I get up to 35mbit but over the course of about ten to fifteen minutes the speed drops down to about 2 to 3 mbps and has even got as low as .4mbps. I then turn the Wi-Fi off and back on and I'm back at full speed again. Curiously the upload speed is never affected.
Any ideas? No other device on the network is affected.

[Q] "slow" Wireless AC speeds

I say slow because they are much slower that a Galaxy S4 and Note 3. At work today we were testing out a Belkin AC router to a cable modem. Using the Speedtest.net app the galaxy's were reliably hitting 200-210 Mbs download speeds. My new One was only able to muster 95Mbs down. I come home and connect to my ASUS N66 router and I'm able to hit 104Mbs reliably. What gives? This makes no sense to me. I verified I had a 433 Mbs link when on the AC router at work, same as the Samsungs, we were all in the same location I even tried standing where they were and holding the phone differently in-case I was blocking the antenna. I never expected to be able to get 104 down at home standing one room and 30 feet for the router. Is there something weird going on with the app maybe?

In WiFi advanced settings, disable WiFi optimization - other uses stated it helped them to increase the speeds.
Settings>WiFi>Advanced

Thanks I read that and tried it to no avail. Speeds were better yesterday at 150Mbs and inline with a coworkers brand new ONE running 4.3. I believe it is just a matter of how HTC deals with packet size (windowing) and not truly indicative of throughput capability. The test runs for a limited time and the throughput increased throughout the entire test. If it ran longer it would climb higher but just how high is the question.
It's a matter of curiosity more than anything as I never need those speeds nor are the repeatable anywhere but in that test"lab" In reality I only have a 100M connection at home and with power boost see speeds of 150 max. I get 100+ reliably (5Ghz N network) to the phone from my main living space and that's nothing to complain about.
I will have to say the range on the ONE is outstanding. My desk is 100 feet from the AP and I was able to obtain 125Mbs reliably from my desk. I didn't have the chance to compare it to the S4 at that distance but I can't complain about that speed.

[Q] Wi-fi Speeds

Hi
Wonder if anyone experienced the same problems as me.
The Wi-fi speeds I am getting is around 30 mb on my nook, although this is a reasonable speed I noticed that it goes down sometimes quite a bit. I belive the nook can only connect to the 2.4g wifi and not the 5g.
In comparison my windows laptop (2.g) gets 50mb
My Iphone gets 55mb and my other Windows tablet gets around 45mb
I now the Nook is quite old now so is it just not able to pick up high fiber-optic speeds or is there a fault somewhere?
Thanks
Yes, the Nook only supports 2.4 GHz 802.11n, with a maximum MCS index of 7.
What does that mean? Wikipedia has a handy table here.
It might look confusing at first, but here is how it works. The maximum data rate depends on three factors (apart from the modulation type):
1. the number of spatial streams (basically antennas, 1-4)
2. whether or not 40 MHz wide channels are supported
3. whether or not short guard intervals (GI) are supported
The WiFi chip in the Nook has only one antenna and supports neither 40 MHz channels nor short GI (at least it's set up that way in our firmwares). Therefore, the maximum achievable data rate is 65 MBit/s.
It can also be lower, if the signal is weak. You can check the current number in Android's WiFi settings, by touching the name of the WiFi you're currently connected to.
However, that's the link speed, the theoretical maximum that also includes WiFi protocol overhead. In practice, you can consider yourself lucky if you achieve about half of that for payload / user data.
So, if your tablet is connected at 65 MBit/s, you can expect a usable data rate of about 32 MBit/s at best (3.8 MiB/s). The final data rate can also be throttled even further by other system components, like bus and CPU speed, etc.
My phone for example also has MCS index 7, but supports 40 MHz, and therefore has faster WiFi with link speeds up to 135 MBit/s. And my notebook has MCS index 15, two antennas, with both 40 MHz and short guard interval, therefore achieving 300 MBit/s (provided of course your WiFi router / access point supports that as well).
Long story short, the relatively slow speed you're getting on the Nook is probably normal and by design.
Thanks for the detailed post.
I am guessing that 30 mb is quite good then in comparison

Your speed is about all its going to get but in comparison to it being bad? Its rather bad...
