New laptop, only XFINITY wifi network works?

Have a new laptop. WIFI works perfect on XFINITY WIFI network but when using "our" WIFI network/signal from Comcast it times out. Almost every time the first page to a website will actually load but any other link clicked it will get stuck loading then timeout. Our network WIFI signal is always at max strength. XFINITY signal varies from half to full strength. All other devices work perfect with our network WIFI. Turned all other devices WIFI off and the Lenovo WIFI still does not load on our network signal. This happens on both Chrome and Edge

So new laptop and only XFINITY network works. Our network can be connected to and has full strength, just the pages timeout.

There was one time I saw this.

In reply to: New laptop, only XFINITY wifi network works?

Or two. The first was when the owner had the same WiFi SSID for both networks. It was odd and he didn't agree he couldn't do that. Had to wait a month till he softened up.

The next time I found the router out at channel 14 so there was trouble. Changed the router setting back to US or NA and that fixed that one.

-> Be sure you didn't install any Comcast or X software on this machine.

When connecting to the xfinity network it opens a browser and requires a login from their webpage. Our network SSID just requires a password on on the internet icon. So do not think XFININTY and our network are the same, if that is what you mean.

Never messed around with channels on the router. Every other device works with whatever channel it is on. Will look into changing the channel for the hell of it.

No software has been installed.

What is this Internet Icon?

In reply to: ....

The icons on stock Windows don't have such. I have a WiFi icon but you wrote an Internet Icon. Let's hear more.

In reply to: What is this Internet Icon?

Bottom right by the clock is a "half line circle" looking icon. Right-click that and our SSID is there, click the SSID and it requires a password to be entered there. In that same list is XFINITY wifi, click that and a webpage pops up and requires an xfinity login. Only have to enter the password once if you save/stay logged in for both.

Icon like this.

Just wanted to be clear about this.

In reply to: ...

I worry that your Infinity login is configuring your Internet settings.

I take it that this is the same on all PCs, phones and such.

It would be very rare to have both the old Comcast and Xfinity systems active as that would have you pay double. When Comcast sent in the new Xfinity box, the old Comcast system would not work any longer.

Are you paying double now?

In reply to: Just wanted to be clear about this.

I only tried the XFINITY wifi after our network would not work on the new laptop. So the issue was before I even logged into Xfinity wifi.

We just have xfinity.

If you just have Xfinity then why would the Comcast

In reply to: ....

Work here?

In reply to: If you just have Xfinity then why would the Comcast

Comcast is Xfinity. I guess xfinity is the name of the cable/internet package. You get your SSID network from Comcast/xfinity (basically for your home) and you can use Comcast/XFINITYS own network (anywhere there is a signal, like your home or throughout the area, depending on signal strength)

The clue then is in your Xfinity answers.

In reply to: ...

When you login to your Xfinity we call that a PORTAL system. If you don't want a PORTAL LOGIN and just want the old way where you connect to your WiFi and get to the Internet then you have to ask Xfinity how to turn off the PORTAL SYSTEM.

I hope you realize...

In reply to: ...

....that each wifi signal needs it's own configured connection? You can't use the connection for the Xfinity wifi to connect to your home wifi.

Collapse -

In reply to: I hope you realize...

Yeah, no I'm not trying that. We just tried the XFINITY wifi to see if it worked, which it does. Our network works with everything else, just not this new laptop. I mean our network does load for example Youtube, but when I search it does not load to the next page and just times out, same with other websites and our network shows full signal. Then sometimes the first page of a website will not load either on our network with a full signal, but on XFINITY network wifi it is perfect.

that instead sounds like...

In reply to: ..

....a problem with Comcast internet service more and not with your wifi signal at home. What happens if you plug directly to a LAN port on your home router? Same slow connections? Is this by cable, or a DSL connection?

Collapse -

In reply to: that instead sounds like...

Laptop has no LAN. It is cable internet.

Im not too familiar with channels. But I did try just the Lenovo and turned the wifi off of all other devices, so should not have overlapped.

Not sure if this helps.

Lenovo does not work
My network
protocol 802.11n
channel 11
ipv4 address

Lenovo works
xfinity network
protocol 802.11ac

Other laptop that work perfect.

that new laptop is 802.11ac

In reply to: ..

signals. That's what the 802.11ac means. Your router is old and slow and only does 802.11n protocols.

Obviously your 5 Ghz connections are working, such as with the Xfinity hotspot. Your old router only does 2.4 Ghz speed. Your new laptop is supposed to be backward compatible, but sometimes that doesn't work correctly. It would be best if you could get an upgrade from Xfinity to an 802.11ac capable router.

For that new laptop to work with old router it must have a separate connection set up in it, and I would also limit it to 2.4 Ghz speed for the local wifi, since there's no local 5 Ghz available from the home router. Each wifi connection should have it's own settings, one for the home router, one for the hotspot connection.

If you can't get it working that way, there is a work around, but involves buying a USB 802.11n with b/g/n connection ability and using that for the home connection on the new laptop.

I suggest this one because it will work both in windows and linux and isn't expensive.

In reply to: that new laptop is 802.11ac

Forgive my ignorance but why would it be the router if all other devices work on it? Xfinity network on the lenovo is 5ghz and works perfect with the 2.4 ghx router. All other 2.4 ghz devices work perfect with the router. Wouldn't it be the laptop network card? The lenovo on our network does not show a ipv6 address on the laptop adapter settings. Would that have anything to do with it? I do not see any option on the laptop to switch 5 to 2.4 ghz.

does it "see" your home router network?

In reply to: //

If it can "see" it, then it should work with it. If it works with the XFinity, but not the home router, then you need to check the settings in other devices that allow them to connect and do the same to the lenovo connection you set up for the home router's wifi.

Not just you.

non overlapping channels of both 2.4 and 5 Ghz

In reply to: Not just you.

Here's one showing how many connections can be made based on the width settings of each channel. Too wide a channel can limit down to only 2 connections on 5 Ghz.
