[Q] Wi-fi Speeds Way Down - EVO 4G Q&A, Help & Troubleshooting

I am fully rooted running netarchy's 2.2 ROM with the 3.7.8b kernel. My speed tests using my home wireless connection are usually 12 Mbs download and 1.5 Mbs upload with my N access point and round 8 and 1.5 with my G router (20 down 1.5 up cable connection). Today, I am getting roughly half the download speed and the same upload speed from both the router and access point. I do not have a computer with wireless to test with, however my desktop is getting 16+ and 1.5.
I am having no other problems with the phone and my signal strength is great. The only other changes I have made recently are updating both radios, 2.15.00.07.28 and wimax 26023.
I have tried older versions on the kernel with no change in my wireless speeds, what else should I be trying?
Has anyone else experienced this? And yes, I have rebooted all of my routers/cable modem, access point and phone.
Thanks for any help
An update, I watched the speedtest closely this time and my speeds starts really high (close to 10) and then quickly throttles back. Hmmm.....

Is wireless N active now since the 2.2 update? My speeds are the same since 2.2, roughly 18 dl and 5 up, but I have noticed the range is better thats why I'm asking if N if active, or did they just give us a better driver. I have not tried to isolate just an N broadcast. But I'm thinking my speeds should have increased if I was connecting with N.....

Painfully Slow Wifi

So I just realized what I had always suspected: my wifi is terribly slow. I've had my inc for 7 months and I rarely turn wifi on at home because its simply not worth the 10 seconds or so it takes to get started. I just did a speed test on my inc and got .85 mbps. My computer gets 27 with Comcasts speed boost but usually around the 15 mbps that I should be getting. I have a laptop in the other room that gets 17, and my ipod touch gets about 10. But no matter what I do, I get less thatn 1 mbps on my inc. The upload speed is about 2.5, where its about 3.5 on the Ipod, but that's not the issue. Does anyone know of anything I can do with my router settings or inc settings or do I maybe just have a bad wifi chip?
I'm currently running OMFGB btw.
yeah, my wifi is pretty damn slow on mine too. sometimes it'll say its getting 5-6mbps with speedtest, while my computer gets 15-20.

Try checking what channel your wifi is using. If you are in a highly populated area (ex. an apartment complex), your router may be on the same channel as several others which can dramatically slow down your performance. You might have a wireless b/g/n router and your laptop can see the n frequency (5G) while our Inc's can only see the b/g frequency (2G), and in that case, that is why your computer is getting better performance. Most newer computers (and some older) can see this 5G frequency, while most mobile devices can only see the 2G, which is why you're phone's speed is slowing down. Try a different channel that is empty or less crowded. It is quite common for many routers to operate on the same channel and newer routers have a function that automatically will switch to the least populated channel. Hope this helps, it has helped me in the past.

Thanks for the response I think this is my problem! I don't live in an apartment complex so I don't think that is the issue but I do think it is my router as I was just at my girlfriend's and was able to get the 5 mbps hers puts out. Any idea how I may go about changing the b/g/n to just b/g? I don't see an option in the router settings. I have a linksys. I now know I'm sort of in the wrong place but any help would be appreciated!
Edit: Never mind got it! Thanks!

Is something wrong with my WiFi?

The other day me and two of my friends were conducting a lil experiment to see which phone had the best wifi download speed using the speedtest.net app, one has the iphone 5 and the other a year old sony xperia phone. We all connected on the same router and when conducting the test they ended up having speeds of 32mbps!! While my phone only managed a measly 15mbps..feeling slighly embarrassed after bragging to them about how my phone is so much better then theirs we did the test again just to make sure it wasnt a fluke thing but nope we got the same results. My question is..is something wrong with my wifi..i mean ive never had a situation where its disconnected but ive noticed that the wifi icon does fluctuate from having full bars to no bars quite alot even if im right next to the router but i havent noticed the performance drop..im just baffled as to how such a amazing phone got beaten by the iphone and a phone thats older then mine with download speeds.

It looks like you have the dreaded Wifi problem. The fluctuation sounds all too familiar to me. Read the topic about this problem in the General section.
Don't worry man.
Forget the wifi issues cause by hardware, it is very rarely and is is very unlucky cases (other comes from user's mind)
For your matter, I have to face the same situation and in my case, I found that the issues comes from channel of the router. Normally, wifi router has many channel could be set with different frequency:
1- 2412 GHz
2- 2417
3- 2422
4- 2427
....
11- 2462
12 - 2467
13 - 2472
14 - 2477 GHz
The HOX work best in Wifi mode G / Channel 14 as I could easily got 54Mb/s. You could try again with other setup of router. Install wifi analyzer app from market and it could help you to find best channel for your HOX.
(remember to update your phone with latest ship rom).

Recently flashed to Boost, data issues after flashing CM11

I finally got my Note II flashed to Boost Mobile using AlpineMan's guide (thank you very much, by the way), and everything seemed to run smoothly (running stock rom), except 3G speeds may have been just a bit slow. I was on WiFi anyway.
After I flashed the most recent official CM nightly, I could still call and text, but the data started to act abnormal. Half the time, it's switching between 3G (which is quite slow) and 1X. The other half of the time, it isn't connected to either one. These changes occur about 3-5 a minute.
According to the speed test, my 1X speed was about 0.13 Mbps download, and 0.1 Mbps upload.
3G won't even stay on long enough for me to do a speed test. Only 1X will.
I could really use some help here, and I would greatly appreciate it.
EDIT:
Never mind, I started fresh from stock, re-flashed to Boost, re-flashed CM11, and now I have solid 3G at an average of 0.96 Mbps.

[Q] T310 wifi performance

I've had my t310 for a while and noticed its wifi performance is a lot slower than my other devices.
I'm running a topnotch 2.4/5ghz dualband router with 100mbit fibre optic connection, theres also a laptop connected via ethernet with a massive harddrive for the whole house.
My PCs get roughly 24megabytes/s for file transfers and 13megabytes/s as download speed through fibre (450mbit wireless). My tablet reaches 7mbytes max on both internet and local file transfer. My S4 gets 13+ on both.
Does this tablet use inferior wifi hardware? Both phone and tablet are connected to the 5ghz signal at 150mbits yet my phone reaches almost twice the speed right next to the router.
Ive messed around with tcp buffer tweaks and different congestion controls but noticed no difference. I've also tried original firmware, modified stock and CM.
Does anyone have some performance numbers I can compare to?
I have the sam issue on my sm t-315, its supposed to be a b/g/n card, bytt I cant get wifi speed above 40Mb/s. My Htc one max gets past 100 on the same network.? Is this a known fact? Is there a fix
Sent from my SM-T315 using XDA Free mobile app

The tablet network hardware is fine. Is it inferior to your desktop computer, the Wifi is not, but yes, it will never keep up the sustained data rate that your desktop can since your desktop probably has several GB more RAM.
Speed test software depends on a lot of factors not just network speed. You should test more carefully. In fact to test the performance of a device, only test locally on your LAN, not the internet. I get much better numbers than yours on the Tab 3.8 on the LAN hitting a local server. You will also likely get much better overall performance on the 2.4 Ghz channels than 5 Ghz unless you are always next to the router.

Not being rude but I did say that I get the same performance accessing local files on LAN and internet which is roughly 7megabytes/s whereas my phone reaches double that with similar cpu and ram specs. The tablet has plenty of ram, I barely ever get close to using all of it so that is not the issue either. 5ghz is faster for me than 2.4 and yes, I am next to the router.
It's not even down to the write speed of the internal memory sinde that reaches well over 20megabytes/s sustained writing which leads me to the only other thing, which is the wifi controller.
Edit: the only reason I mentioned speedtest results was to rule out the possibility of the source drive being slow on my local network. I tested the speed both using speedtest and downloading an OS image from Microsoft

Well I think not, I test with the same prog on the same server and the same network. It got to be the tab that is faulty configured. My guess is either the radio or the kernel or both.

Pixel WiFi issues, anyone else?

Like the title states, since opening the package I've had very bad wifi performance. If I do a speedtest my ping is 3ms and 300 download, but i'll constantly get no connectivity with the wifi on. Pixel 2xl beside me works fine. If I shut off wifi, everything works. I've even done a factory reset, same problem. Anyone else have this issue?
I concur.
The distance on it is very crappy

Except I have the Google mesh kit and literally inches away from it LOL
Your complaining about 3ms ping and 300mbps download...lol cmon
I'm about 15 feet away from the router and getting poor to no signal strength on 5 Ghz. My S5 and Nexus 10 are rock solid. This might be a deal breaker.
Edit: I have a turris omnia router with horsehair plaster walls. Will enable 2.5 and see if it is better.
I haven't seen any issues with mine. I actually have a stronger Wi-Fi signal with it throughout my house than I did on the 2XL.
I'm having WiFi issues too...
I started noticing them right away but i used the cable to copy my Pixel 2 XL files to the Pixel 3 and figured it was the background processes going nuts and causing problems. But after about 15 hours it was still going (i was up all night sick, probably because i purchased a phone with a notch). So I figured i'd try again when it was done.
So this morning i went back into the living room after it finished and the problems continued. I have a router mounted to the wall up in the corner by the ceiling. Its within 10 feet of me, and still my wifi works intermittently. I'll try to load google.com to do a search and it fails, i'll reload 4-8 times before it finally loads, i'll enter my search and hit the search button, and it'll fail. So i'll hti the reload button another 4 to 8 times before it loads.
Using YouTube, the first two thumbnails load, but nothing else. Something is wrong with it! Everything that uses data is doing this, and when WiFi is off, the issues are all gone.
Yep! Exact same problem. I had to reserve an IP for my phone just to get it to connect at home. Every now and then I have to toggle off and on the WiFi cause it'll stop working. I'm glad I'm not the only one. Also glad someone tried resetting too, I almost did myself. Hopefully it's software and Google fixes it. If it's hardware I'll be pissed.

On my Pixel 3 XL, my speeds are fine. It's just that I can't connect/stay connected. This has been happening since I took it out of the box 3 days ago.
From my post on this issue in the Pixel Community over in the Google Product Forums:
"Just recently, I came back home and the phone refused to connect to the wireless network (no wifi "radar" icon in the notification area at all). I sat next to the wireless access point and opened up Settings > Network & Internet > Wi-Fi and it said disconnected. Going into the Wi-Fi area to have it search for networks it would find none, then find some, find all, find all but my own access point, etc. (my old Nexus 6P doesn't have that problem).
When that settled down, I chose my access points and looked at the details. Both my 2.4 GHz band and my 5 GHz band were full strength and saying "Excellent" in the Settings next to Signal Strength. The 2.4 GHz band had a Link speed of 144 Mbps and the 5 GHz band 866 Mbps, about the same as what I see with my 6P. I spent 10 minutes tapping on one or the other trying to get connected. Sometimes they would, but then drop. Other times, they wouldn't. Then the wifi scan dance would begin again. Again, nothing similar on the 6P. I finally got stable connections (I ended up having to reboot the phone to do that) and ran speed tests from DSLReports.
On the Pixel 3 XL, I got my Cox rated speed of 100 Mbps down and 10 Mbps up for 5 GHz and 66/11 for 2.4 GHz. On my 6P, I got 79/10 for 5 GHz and 69/10 for 2.4 GHz. So, if I can actually connect, I'm not seeing slow Wi-Fi speeds. I'm seeing darn good ones. It's just that I can't get the thing to connect. And when it does, it doesn't want to stay connected."
My Galaxy S5 outperforms both Pixel 3 and XL on 2.4 and 5. They can barely stay connected in the room adjacent to the router. This is sad. Will likely return both and try the 6T.
