Sounds like your router and xoom aren't playing nice. Mobile wifi uses power save modes which aren't always properly supported in router firmware.
A few things you can try:
Set to pure A/B/G or N (N is best) no mixed protocol modes
If on N, set short guard interval off and set channel width to 20mhz
Set security to WPA-2 AES, no TKIP
upgrade router firmware or reboot it
If the network ever drops and doesn't reconnect, try https://market.android.com/details?id=org.wahtod.wififixer
It will detect the drop and automatically reconnect.

Out of curiosity,
[*]If on N, set short guard interval off and set channel width to 20mhz
Whats the reasoning behind this and do you have a source?

Thanks for your answer my router is a belkin f5d7230-4
how do I change these settings? I cant find it anywhere in routers settings
security level is wpa2 only
i have the latest fw
EDIT: nvm I found them, I only have: 11g only, 11b only and mixed (g and b) so I put it on 11g only I enabled turbo mode (what the hell that is) and extented range.

40mhz width isn't supported on any Android device that I'm aware of. Auto detection of width seems to be problematic in my experience.
Short guard interval is terrible indoors due to radio echo.
Source is a decade plus of setting up wifi networks.
I forgot to mention enabling long preamble, which really helps with mobile wifi clients as they spin up from low radio power modes. That's more important than short guard interval.
Daft question ... you haven't got your wifi advanced settings set to kill the wifi when the screen sleeps have you ?

That's not default as of Android 3.0.
Good question, though!

nop I already disabled that. So far so good I also installed Wifi fix app from market, let's see how long it will last.
Still no luck :/
I get dc with ICS eos rom to...any more suggesitons?
Which router is causing (potential) trouble?
- I have both U-verse and Linksys (the old-model work-horse)
And... I'm also suffering from intermittent wifi issues. But, then this is (for me at least) a good thing as it keeps me focused on work and AWAY from youtube (etc).
Observable problem is that wifi simply drops when viewing youtube.
I had assumed either there was an issue with u-verse or Zoom - though wasn't pressed for an immediate fix since the Zoom did well at non-streaming web and email.
I know this is a long time after your question but if you are still having the issue I resolved mine. I just upgraded my home wireless and my xoom started having horrible download speeds. Ends up it cant handle AES and doesn't let you pick what encryption you want - it appears to use the highest encryption available on the ssid (I had tkip and aes enabled). When I killed AES and only left TKIP my xoom download speeds went back to normal. Issue is, you need AES for N wireless so if you can create a separate SSID for your xoom only, you can have the best of both worlds, N for everything else that supports it, and decent speeds for your xoom.

I think it's dangerous to assume that experience with your Xoom on a specific access point is universal.
Problems tend to be caused by a specific model/firmware of access point interacting with a specific Android device, with wifi drivers and chips being the most important part of the equation.
In my experience on many devices, AES is much less likely to be problematic than TKIP. TKIP is a less secure and less desirable protocol.
I am running N/AES on several access points with my Xoom with no link speed issues.
So I've validated that often (but not always) if Bluetooth is turned on, then wifi will not work on my N5. I'm almost positive that this began with Marshmallow. I am sure that it is not working in 6.0.1. I'm running Cataclysm/ElemX latest 6.0.1 versions.
I've been keeping Bluetooth on all the time for the last 4-5 months to sync up with my Garmin Vivoactive. I notice now that when I get home from work, where wifi should normally work just fine, I have to turn BT off in order for wifi connectivity to work. Settings shows strong signal and connection to wifi home network, but throughput is either at 0 or very slow (i.e. 2-3k per second).
I see that someone raised an issue on this back in October. If you see this on your device, please add a comment to the issue:

Is anyone here also experiencing the same problem with me?
I found that from time to time, my XZ Premium losses WiFi connection and can't find any hotspot until I turn on then turn off airplane mode, or just restart.
Here are the screenshots form my S7 edge (SM-G935F) and XZ Premium, they were next to each other and very close to the router.
Please help me, thank you.

are you using 5G? if you are, you need to update the wifi channel and band through your router settings. that's what i did with mine and now i don't have that intermittent wifi connection anymore.

Sure, thanks, I will give a try, and can you please tell me which channel and band should I use?
Anyone found a solution for this?
Wifi was spotty before the Android 8 update but now it's almost unusable. Every now and again it will just stop showing wifi connections, toggling wifi on and off might show a connection or 2 but it will either disappear or just say "Disabled" when trying to connect to it. Reboot solves it for a little while.
Usually use 2.4Ghz wifi with a variety of router brands.

Happens here on Android 8 as well, quite annoying to be honest. Sometimes drops the connection for no reason, and then when I click on WiFi settings, it doesn't show any connections till I turn WiFi on and off and even then it'll only show 1 SSID, turning it off for a while longer and then turning it back on brings back the rest of them and then it'll connect, but it's stupid how I have to keep doing this every few hours.
I set my 2.4 and 5 GHz bands to different names and join only the 5 GHz, and I don't get drops. On Oreo rooted.
i have xperia xz premium with Oreo 8.0 I encounter the same problems when I'm connected to my wifi, suddenly the data connection is blocked, and when this happens I have to turn off and on the wifi symbol to restore the connection. I do not understand why this happens. My phone is updated to the 47.1.A.5.51 system with November google patches. My modem is Billion Bipac 7800N
So it seems to be a common issue, anyone know if Sony is aware of it?
Where can we complain? It's their damn top of the range phone and it's most basic function isn't working right.

Knock yourself out. I've had more than one device with the Snapdragon 835 behave in this way, so I think it's a chipset issue.

Do a Google search for WiFi and Oreo and you will see that this is affecting multiple cell phones.
Do they all have the 835 chip in them???
I think it is an Oreo issue.
I have no such problems and I have Oreo and the 835.
Try disabling IPv6 on your router.
This is still OS/firmware issue but this temporally fix the issue

I found the solution:
My network works with two devices:
1 ZTE Router (2.4GHz)
1 D-LINK Repeater (2.4GHz)
In the router my XZ Premium works nicely, in the repeater happen exactly what you said, Connect apperars "no internet" after 1 second and wifi on Smartphone is automatically disabled or wifi stay enabled, but says "disabled" on network.
So.. I checked the wlan settings of the two devices in my network exhaustively item by item and I changed the devices settings about 20 times, I and I found that none of the settings matters (wpa or wep, 5Ghz or 2.4Ghz, Bandwidth 20Mhz or 40Mhz, type of network b / g / n, nor channel 1 to 13) just ignore this.
What REALLY MATTERS is a option in the advanced wlan settings, called "Fragment Threshold" this value was at 500, I changed it to the maximum (2346) and my XZ Premium started the connection instantly. Explaining: increasing this value defined that the packet can be up to 2346 bytes before being fragmented, so we deactivate packet fragmentation, reducing overhead and ensuring the best transmission rate possible, so this option determines the size of the frame.
Put simply: Go to advanced Wlan settings, locate "Fragment Threshold" and change to the highest possible value. That worked for me =)
worked for me
1- turn off wifi in being wifi settings ie where you view your wifi networks
2- select "scanning settings". it will show once you have turned your wifi off
3- turn off wifi and bluetooth scanning
4- go back turn wifi back on and enjoy

It did not work for me, unfortunately.
I know I am reactivating this thread after nearly 3 years of the last post but did anyone find any effective solution to the Wifi issue?
If somebody need to use some wifi mesh network (mesh, wifi extenders, multiplus accces points with same ssid, etc.) maybe must not upgrade to oreo. Google for "wifi roaming oreo issues", "wifi mesh oreo issues" and "wifi oreo issues" and you will find many problems like I am having now. My house network has a main wifi router and two wifi access points conected to the main one by ethernet cable. After oreo my moto x4 can´t do wifi roaming like before. Manytimes it is conected but has no internet with an exclamation mark on the wifi icon and sometimes I have no exclamation but the internet can't work. My other devices are working well, roaming well over wifi and the only change was the oreo update in my X4. This bug is not related with de google cast one and is plaguing various devices after oreo update, just google like i said.
The issues are afeting One Plus 3/3T/5, Essential Phone, Xperia Xz... See this links:

I have four handheld Android devices and, currently, 3 standalone WAPs plus Verizon's FIOS router.
.
None of the four devices can maintain a connection to any of the standalone WAPs or the router for more than a half-second or so: they solicit the PW, Authenticate, connect briefly, and then drop the connection.
.
I normally have only one WAP, but added the two just to make sure the problem was not in the WAP. Ditto Verizon's router, whose WiFi is normally turned off, but turned on now for troubleshooting.
.
For the life of me, I cannot think of any changes I have made in the week leading up to the onset of this problem.
.
One of the standalone WAPs is an Orbi Mesh system, but currently with no satellites - the satellites having started to act weird with onset of the problem and therefore having been turned off.
.
I also have two instances of AndroidTV running: one on a Sony Bravia TV and the other on an NVIDIA SHIELD box. And, weirdly, both of them are able to hold a WiFi connection - but UNABLE to hold a Ethernet cable connection. Same appearance as the handhelds over WiFi: connection gets dropped, only almost instantly so the screen just kind of vibrates with the connected.
.
If I turn off all standalone WAPs, leaving only the WAP in the Verizon router, the problem persists - with the Verizon router's WAP on channel three and, according to the WiFi Manager Android app, no competing signal sources on channel 3.
.
The problem persists even with the handhelds within 10 feet of the various WAPs.
This started about a week ago. Before that, no problems. And I don't *think* I have changed anything.
Right now, the only thing between me and hiring somebody to troubleshoot the problem is the weirdness of the problem - and the fear that their billing by the hour could cost me too much.
Can anybody point me in some direction?
