Hi everyone,
I have my Nexus 7 connected to an verizon actiontec router. I am getting terrible wifi with WPA2 security enables. Loading websites takes forever and youtube constantly gives network error. I changed the encryption to WEP and its not disconnecting as much but I would prefer to run WPA2.
Anyone have any suggestions on what is causing the lag and disconnects? 2 laptops and 2 android phones no issues.
Try switching to 802.11g. The N7 is quite flaky in 802.11n mode with a lot of routers.
If you are using WEP, you are in effect forcing 802.11g mode, since 802.11n requires WPA2.

Thanks for the reply tni,
Is this a hardware issue or a software issue? Could hardwiring and IP number and switching back to WPA2 possibly fix the issue?

Driver and/or firmware. The Nexus 4, which has pretty much the same Wifi hardware, also has quite a few complaints about Wifi issues.

It's highly unlikely that a fixed IP will make a difference.
Not sure if that came across, but you can use WPA2 with 802.11g (you need to configure that at the router).
Well I changed the router over to WPA2 and then in the advance preferences set it to 'Legacy Mode' to support only 802.11bg and the tablet seems to not be having many hang ups even with youtube. I'll post back if anything changes. Thanks and hopefully this helps a lot of people out there.
I'm using N7 2013 with two different routers,
Both with WPA2, and 802.11n.
No problems at all.
Well, I just did a heck of a lot of work on the IEEE 802.11 protocol suite. I am in no way an expert, but I picked up a bunch of interesting factoids.
- In the 802.11n protocol implementation, all devices must have 802.11n supported NICs. This includes all the clients, not just router. If you have even a single device that is doing legacy 802.11b/g while all the other client NICs are doing 802.11n, then the router will not do 802.11n for any device. Yes, all or nothing deal and the router does not show it. I used Wireshark to confirm this situation exists by drilling down a ton of 802.11 data frames. Despite the router staying set in the drop down menu to 802.11n, under the hood, all the devices dropped to 802.11g.
- Even worse, I know I have clients and router NICs that all support 802.11n, yet I get dropped into the 802.11g protocol. To try to find out what happened, I started from scratch. I put my router into 802.11n which lists it as "performance", then added a static IP to my Nexus 7. I immediately had 58Mb/sec. since 58Mb/sec > 54Mb/sec, I figured maybe I did get 802.11n this time since 802.11g gets 54Mb/sec in optimal conditions. When I went to check which protocol my Nexus 7 is using, I moved it in front of me, a distance no more than 18 inches, and saw my signal drop to next to nothing. I pulled up the Nexus 7's WiFi advanced settings to find out that I now only have 5Mb/sec and the protocol is now 802.11g. This means while roaming, if you hit a sufficient enough degradation in the signal, the Nexus 7 drops your 802.11n status like a hot potato and no, you can't get it back unless you reset everything. I mean at least, to date, I have not found a way to keep a device configured to stay with 802.11n even if the bandwidth drops.
Since I was given a drop down menu in my router as to which protocol I wanted to use and since the 802.11n specs say it is all or nothing, I thought that the router would enforce 802.11n and not allow a legacy NIC to connect to it. This is far from the case. Why they even give us a drop down menu if they are always going to do 802.11b/g/n anyway is beyond me.
Now that I have seen Nexus's wireless protocol drop from 802.11n to 802.11g outside of my control, I want to find all devices that misbehave like this and see if there is anything I can do to force the client to stay on 802.11n. Obviously, I also have to eliminate dead and near dead zones.
Just thought I'd share the all the fun I've had getting to this abysmal point.
I will dig into our smart phones and tablets another day to see if I can force it to stay with 802.11n even its Rx signal attenuated for a few seconds.
I hope this helps others and if your experience is different then mine, I'd love to here what your findings are.
You may be fighting interference not only from the neighbor's WiFi, but appliances in your home. Possible sources for rf noise would include dimmer switches, CRT and plasma screens, microwaves, cordless phones. An rf detector can be bought or built or an am radio tuned between stations can work.
I've seen anywhere from 5mbps to 300mbps connect speed, it can change in one session if the router dynamically adjusts throughput. Also, there may be a power level setting in the router setup to get your signal farther above the noise floor.

An easy rf detector: single coil electric guitar pickup and cheap practice amplifier sourced from a guitar shop. Ask the guitar tech for a good used p/u, they swap them out all the time.
The wider channels used for faster throughput will be more susceptible to interference than the g standard,IMO.

Is it possible ? I have been disappointed with the browsing speed on my TP2 and thought it might be something to do with MTU settings or something like this. However, last weekend I decided to change my router mode from 801.11b/g to 801.11g only. WOW, suddenly my browsing was perfect (the same speed as browsing with my laptop)
So I wondered if it's possible to set something on the TP2 to allow it to connect at g Only - for when using in areas which have a Free Hotspot (like Cafe's or Hotels), since I cannot control the speed that they allow me to connect at.
It's very possible that my TP2 was connecting originally at g speed but that rates were in some way competing against each other.

WM will normally default your connection to the better of the two choices. If the option is between b or g, the connection would default to g. There are some things that could be affecting your connection, however. This is most likely a problem with your router broadcasting both signals at once. If you have no use for a b channel, then have it simply focus on sending the g channel.
This is exactly what I have done - shut down the b channel. However, I am trying to ensure that I connect with g ONLY whenever I find a Hotspot in public places.
C
Maybe the problem with browsing speed isn't your phone!
Better check if you are in an area with lots of wireless networks... Try to set your router to use a channel which is 3 channels distance from other WiFi networks.
For example if you have networks on channels 1,3,5,11 you should set your router to use channel 8.
Also try to set "802.11G Protection" to ON, if your router has it!
Any solution? (I know it's old, but I also want to restrict to 801.11g on my android tablet only and I have found nothing on the internet).

The issue is not with the phone in this case, but the access point. When running in mixed mode, data transfer speeds on wifi access points slow down unless they have multiple dedicated radios. If you want the faster wifi speed, just don't use 802.11b. It's antiquated anyway, especially considering we now have not only g, but n and ac standards on the 802.11 rfc.

i've noticed, however, my phone's (samsumg g-s5) battery drains much quicker when connected to 802.11n network compared to 802.11g. there is no real need for more than 54 Mb/s on my phone, but on my laptop there is. therefore, a way to restrict the phone to use only 802.11g in a mixed-network environment would be beneficial.

As far as I know, you can only restrict the mode of the access point, not the phone. I have yet to see any wireless client device, in fact, that lets me restrict which radio mode it uses, save perhaps some homebrew stuff running embedded linux.
EDIT: Pardon the grave-dig. I had been off the site for a while and only just noticed the above reply to my posting from last year after having last night posted a question of my own.
I'm having WiFi problems with A100 (w/ stock Honeycomb 3.2).
I have a Netgear WNR3500L wireless router (currently working in N/G mixed mode, but have tried all other modes as well) with DD-WRT v24-sp2 (08/07/10) mega firmware.
I have my router behind a wooden wall and the WiFi coverage with A100 is only about 5-6 meters! Go anywhere beyond that radius and it keeps losing the connection.
Have tried different modes and channels on my router, but nothing seems to help.
All my other (10 or so) wireless devices work flawlessly and have a very stable connection in all areas where the A100 doesn't.
Anybody knows if there's some kind of patch or workaround for this problem?
(I've already read suggestions to use static IP instead of DHCP assigned one, but that just a silly suggestion IMHO.)
Thanks!
U got toe same problem... On 2 routers

What is the received signal level reported by the A100 compared to the other wireless devices at the same location?
For Android devices, the best tool is WiFi Analyzer (along with its connecter libraries).
For a Linux netbook or laptop use iwconfig to get the rx level.
Any level greater than -80dBm should provide a stable connection. WiFi Analyzer will show you interfering access points and suggest the best channel.
If the A100 reports consistently lower than others, I think you have to replace it.
Thank you for your reply.
Yes, it has about 10 to 15 dB weaker signal compared to other android devices in the same spot. The signal on A100 is jumping around between -85 to -70dB.
I guess I'll take it back to the store then
I had terrible wifi problems when I first got my A100. It kept kicking on and off so I couldn't download anything. I changed the settings and this is a permanent fix for me so far.
I long pressed the wifi network I was on. I selected modify network. And then all I did was change the IP settings to static. I hope this helps others.
I took the Iconia back, got a refund and bought Sony S1 tablet instead.
And it rocks At the same spot, where Iconia kept loosing the wifi connection, the S1 has full wifi bars.
That was my first experience with Acer devices and probably the last one also.
Hey all. So heres my deal. I have a Linksys E3000 router and an Edimax Wireless Extender I just picked up. I got this since in my house, the router is on one side of the house and so naturally, on the other side, I get 1 bar of wifi strength. Was hoping to improve that. So what I wanted to do was have both units have the same SSID and have the devices automatically switch between the physical devices (same SSID) as I get near them. This didnt work. In fact, both my S3 and my Nexus 7 kept getting confused and dropped connections often.
So now Im trying it where they have different SSIDs (lets say Router1 and Router2) so no conflicts. The issue I have is this. I want both my S3 and N7 to AUTO SWITCH to the better signal SSID. Im running Cyanogenmod 10.1 on both devices and I see in the adv wifi settings something about, 'Only connect to a network where strength is GOOD'. This seemed to be the answer, however it doesnt actually work. 1 network shows great and other shows fair and it still wont switch.
Wondering if there is any other way around this? Otherwise this extender is basically useless to me as I dont feel like constantly switching my wifi networks as I walk across the house. (wow I sound spoil when I say it like that lol)
Thanks all
Is it configured for Universal Repeater Mode?
When you say "it" are you referring to my router or the extender device?
The router BTW is a Linksys e3000 with dd-wrt and the other unit is edimax 7348rpn. I believe that's the right model. Its a little plugin unit. Thanks

Hi,
I'm on my second P2XL (Panda). Both have had issues where they constantly and apparently disconnect on Wifi.
I have a Virgin Media superhub 3 (tried turning 5ghz off), also a TP link range extender plug. Seems to happen on both devices, it disconnects when I'm right on top of the Superhub router.
Any suggestions?
Thinking it must be the router, any suggestions?
would it be worth renaming either the 2 or 5ghz ssid?
I am a wifi newb and have the hub set on factory settings.

I think you are correct on the issue being with the router, and since the repeater gets its signal from the router the repeater is likely not to blame. Changing the SSID would not help. I would first ensure your router (and repeater) is up to date with the latest firmware. My Netgear router comes out with new firmware 2-3 times per year fixing bugs. TP link offers new firmware but not very often. Another solution may be to change the channel the Wi-Fi is using. Usually set to auto, you can change both the 2.4 and 5 Ghz band channels. It could be interference from your neighbors is causing an issue. There are several Wi-Fi apps you can use to find the least congested channels in your home. WiFi Analyzer is one.
If your router is up to date and still causing problems on different channels, you should consider replacing it with a well supported model. No doubt you have used your phone on other Wi-Fi AP's and not had a problem. If you've tried the above with no success, do some research HERE to find a new router.

FIXED - For me, my router was pumping 2.4 & 5 ghz as same name. I renamed the 5 ghz, forgot connection on phone and connected to the "new" 5ghz.
No drops since.
Think the phone was getting confused when it was at the far reaches of the 5ghz connection.
Hi!!
I just bought a new tab s4, and I can not connect it to the 5ghz wifi network. It connects, but says connected without internet. The 2.4GHz network connects perfectly.
PS. Sorry for my English.
Same issue.
My tablet is TIM branded.
Same issue, it connects on 2.4ghz but not on 5ghz...
Anyone?
HI peep's mine is connected to 5 GHz and it’s working flawlessly, it’s showing a connected speed of 866MBPS!
Quick questions, did you try a reboot router and Tab S4 once connected to 5GHZ ?
Also are you using separate WPA2 PSK key ?
As some routers can’t handle separate keys, keep the Wi-Fi key same for both channels i.e 2.4GHZ and 5GHZ!
Does it get ip address from the router/dhcp server you have?
I don't have access to a 5Ghz wifi right now. Next week I'll try the tablet and I'll try everything you said. If the new tablet has the same problem of course, I hope it goes well.

I have the same problem and I noticed that it came with the Anroid Pie update! 2,4G is working fine in my S4.
I have another tablet Samsung Galaxy Note 10.1 2014 edition and 5G Wifi is working flawlessly.
Might it be software issue in Android 9?
My basebandversion is T835XXU3BSF4, kernel 4.4.153-16124683 #2 Fri Jun 14 2019.
My Tab S4 was ,finally, updated to Android 9. 5GHz working fine. Both 5GHz and 2.4GHz working fine...
All good here...
I got one coming in the mail and will report back on my success but if you don't get internet trying setting your dns manually to Google's public one for testing. 8.8.8.8 Could also be related to the channel the router is using for 5ghz.

Okay, so I got a new tab s4, and I have the same problem. At the second floor of my house, I don't connect to the 5Ghz wifi. I have separated bands. I tried changing the channel... I don't know what else try.

5GHz WiFi has less range than 2.4GHz, maybe the signal strength is not enough at the second level. Use the lowest frequency band available, move the base unit to a place less obstructed etc. This does not sound like a device issue.

Yeah, I know, the device issue is that all my other phones, computers and devices are able to connect to the wifi. I enabled the smart wifi and it looks like it's going better, the tablet is able to get better download speed.
