Call 1-800-comcast and ask a rep to *roll and re-provision* the modem. Also ask them to confirm that the provisioning and account data in their database is correct and complete and that the correct configuration / bootfile for your subscribed to speed tier is being pushed to the modem.
I just switched yesterday from RCN where we had 50 Mbps internet and always got 50 whether wired or wireless. I was lured in by the 150 Mbps Blast internet, but am only getting <100 wired and about 50 wireless. I called Comcast and had the rep do what you recommended above. He said everything was correct but he updated the bootfile anyway. He scheduled a tech appointment for Saturday.

First for full speeds wired, you need a gigabit network card in your computer, many, even brand new ones only have 100 adapters in them.
There are a lot of computers that won't do full speeds wifi and have lower speed wifi adapter hardward, configuration and driver issues. There is a good possibility it's the comptuter and not the Comcast connection.
We see it here all the time. Please share details on the wired and wifi adapter cards in you computer as a start. Share the model of the gateway.
Thank you. I updated my signature with my current settings. We also have a couple of android phones and iPhones in the house.
Make sure you have placed your gateway in full bridge mode as a start. Connect the router to LAN port 1 to use your own router and not cause a double NAT condition.
There are many configurations of your laptop, the best I can tell it does only have a 10/100 wired adapter, so you will never get more than close to 90 speeds.
The wifi adapter might be a Dell 1707 adapter which is a B/G/N 2.4 card. It might take some doing to get any real speeds out of it, you might get 70 down with updated drivers and configuration.
Once the rourter is configured properly, you might want to look into a USB dual band A/C adapter instead of using the internal adapter and connect to the 5.0 network on the router.
Router is connected to LAN port 1 of gateway. How do I access the gateway to check if gateway is in full bridge mode? Thanks.
You can also tell by what IP your router is getting on the WAN side, if it's a 10.0.0.x address, the gateway is not bridged. If it's a Comcast public IP, then the gateway would be bridged properly.
I hit a snag. The gateway crashed when I was attempting to enable the bridge. Now I don't have any internet at all - wired or wireless. I am using my cell phone as a hotspot to type this. I tried resetting the gateway but that did not help.
What should I do now? Thanks and Merry Christmas.
Press the indented reset button on the back panel for over 30 seconds to get the gateway back to factory default.
There are installations where you can use one device for phone only and one for internet only. This depends on the wiring in the home and how easy it is to backfeed the dial tone into the inside phone wiring.
As an example, if you had the gateway in the upstairs bedroom where the computer is, but there is no phone jack in the room to backfeed the dial tone, then that would be an example where the installer would place a 2nd device for the phone only near where the phone wiring is terminated or close to the interface box on the outside of the home. Each home is wired differently, but for most there is both a coax jack and a phone jack in the same room so the inside phone wiring can be accessed close by.
A 2nd example would be when there is a home alarm where the installer needs access to the line side of the RJ31X for the alarm panel so the panel can dial out. In this case the installer might not have any choice but to place the telephone modem near the jack for the alarm panel so the panel can seize the line. Having the gateway here might very well have a difficult time to give the customer a good wifi or wired connection. Then a 2nd unit would be installed in a prime location for the internet services.
Comcast tech came and proclaimed that our service is good. He plugged his MacBook into my ethernet and got 180 down. He said that he preferred my ASUS router over the gateway. So after he left I enabled bridge mode on the gateway and reconnected my router, but I can't get any internet through the router. What am I doing wrong? Thanks!
When you switch from router mode to bridge mode, you need to power cycle the gateway so it reconigizes the new router, which must be on LAN port 1 of the gateway.
You might want to fully reset the router and start over with that too.
Now you can work on getting faster speeds now that it's the laptop's issue. Look at those USB AC wireless adapters as a start. I see it all the time now that the Comcast internet speeds have passed up the computer hardware's capabilities.
Plug in the laptop's ethernet port directly to the LAN port 1 and power cycle the gateway and see if you can get to the internet as a test.
If the bridge mode is off and your in router mode, then you should be getting a 10.0.0.x IP address on the computer on any and all of the 4 LAN ports.
If your getting a public Comcast IP on LAN port 1, then it's in bridge mode.
In Windows, go to run and type in cmd and run ipconfig and see what the computer's getting for an IP address.
With bridge mode disabled, I plugged laptop into LAN port 1 of the gateway and ran ipconfig.
IPv4 address was 10.0.0.231.
ASUS router is not in use.
Step 3, test speeds with the computer connected to LAN port 1. Check that your getting a Comcast public IP. Start / run / type in cmd. The DOS box comes up. Type in ipconfig and see what IP address your getting, it must be anything but a 10.0.0.x IP range.
If your getting a public IP, then connect the router to LAN port 1, power cycle the gateway and configure the router.
Ok, I've completed steps 1-3, and have a public IP address.
So I will attempt to configure the router again. Wish me luck. Thanks.
Can you access the router's settings and look in the WAN side, see if it's getting a Comcast public IP address, DNS and gateway settings?
If ther router is set on automatic or DHCP, then power cycle the gateway again. The router must pick up the public IP network settings passed through the gateway so the computers get internet access. Is the WAN LED on the router on or blinking?
If your on the network map page on the router is internet status connected or disconnected?
I bought a D-Link DWA-171 Wireless AC USB Adapter:
I'm up to 80 Mbps using the 5 GHz band.
Do you think this is as good as I will get on this old laptop?
D-Link hasn't released a Windows 10 driver yet, so maybe the 8.1 driver is good enough. Check the adapter settings and look under the advanced tab for wireless mode settings or other settings to confirm your on AC and not on auto.
Keep checking D-Link for when the Windows 10 driver is released.
I think you should get full speeds if the driver is correct and the adapter settings are correct.
I know the Netgear A6100 AC USB adapter will do full speeds, even on a older 2008 HP laptop on Windows 10. This adapter does have Windows 10 drivers available.
I checked the advanced tab and it was set to auto, so I changed the wireless mode setting it to AC.
Are there other settings I need to adjust?
My laptop crashes when I reboot with the D-Link adapter plugged in. It seems to be ok if I unplug the adapter before restarting. I just plug it back in when the windows login screen appears.
I just speed tested again and got 118 Mbps.
Do you think that D-Link will update drivers soon? Otherwise, I'll have to return the D-Link and buy the Netgear adapter that you suggested. Thanks for your help.
I have no idea on when the drivers will be updated as they should have been done by now, but you might want to return it for the Netgear.
I just ordered a Netgear A6100 AC USB adapter. Thanks!
I installed the A6100 and got 128 Mbps after enabling AC in the wireless mode tab. Is that as fast as I should expect?
It's hard to tell if your going to get anything faster, but I believe you should be somewhat faster. Now is it the router settings, the computer / OS or the wifi adapter settings, I don't know what else to recommend.
I just upgraded to 150 speed tier and on wifi with the A6100 I am getting 179 down on a 2008 HP laptop with a fresh install of Windows 10 pro.
Here's my settings
Enable Adaptivity - auto
QoS Support - Support QoS
USB SF Mode - disable
USB Switch Mode - Auto
VHT 2.4G IOT - Disable
Wireless Mode - IEEE 802.11 ac
I almost got 150!
A problem that I have now is that my wireless HP MP printer is on the 2.4 band. What solutions do you recommend to be able to print to it? How would it work if I USB the printer to the router? Thanks.
Printers are almost always on 2.4, it doesn't matter if the printer is on 2.4, the computer is on 5.0 or ethernet. It should all communicate between the bands and ethernet in and out of the router. You don't want to communicate using peer to peer but use infrastucture mode and as long as the printer has a IP, the computers should find it.
If I go back to the old 2.4 wireless network with the built-in wireless adapter, it finds the printer. Using the Netgear wireless adapter, I get printer offline error messages.
I know that I need to change something in the router's 5.0 gHz settings to allow it to see the printer, but I don't know which setting to choose.
Success! I reinstalled the printer using IP address using the wireless 5 connection. Now the printer works fine!
