wifi issues with laptops and windows 8

i recently bought a toshiba satellite radius and a dell inspiron 15 7547. Both are having major degradation of wireless speed when I move 15 ft from router (couple of internal walls in between). I have an older dell and an acer that dont have any problem with the distance.

Laptops are new and have latests drivers. The only diff is the new laptops have windows 8.

I have Verizon fios 50/50 speeds

This is most likely a driver issue.

I would download the latest drivers for your WiFi cards (not necessarily the manufacturers driver), if you know who makes the card in your system I would get directly from them, if not then got to the Laptop manufacturers support page and download it from there.

Follow these steps:
1. Open "Network and Sharing Center"
2. Click "Chang Adapter Settings"
3. Right-click on the adapter in "Network Connections" and its "Properties"
4. Click on the "Configure" button then on the "Driver" tab
5. Chose "Update Driver," "Browse My Computer" and then "Let Me Pick..."
6. There may be more than one driver: a Windows 8.1 version and an ODM driver
7. Chose the ODM driver

If that fails to correct the issue I would also try looking at the adapter power settings:

 1. Open Network Sharing Center
 2. Click Change Adapter Settings
 3 Right click on WiFi and choose properties
 4 Click Configure
 5 Choose Advanced
 6 From the list below choose minimum power consumption and change value to disable
 7 Click Ok

Depending on your system you may have different options for steps 6 and 7 similar to these:

6. On "Roaming Sensitivity" change the value to Disable
7. On the "Power Management" tab, deselect "Allow the computer to turn off this device to save power"

Another approach here worth mentioning may be that your systems are using a WiFi/Bluetooth combination adapter, if that is the case it may help to disable the BT functions if you are not using them. Other users have found this to help in some cases.

Disabling BT on your device will depend on you system, some have buttons some have switches but to truly be sure I would disable the feature in Device Manager.

I hope you find this information helpful.

Generally wireless cards will change what they are using N, G, B, A when they get farther away have more interference they use the older wireless that has longer range but lower speeds. That could be an issue but you might be able to change the settings on the products to only use N or G... Or perhaps they are only using wireless N which if I remeber correctly prefers a more direct line of site for the signlas but G I believe is more "bouncy". I would check to see what standards they are on. The other option would be to put a repeater on the other side of the wall, sometimes a second wireless access point is nessasary though you never want more than one wireless node hop if you can help it in a network. Also take in consideration that if you have a cell phone don't set it right in between the laptop and the wireless signal as that can sometimes cause interference.

Do you have a removable USB wireless that you can test it with?

I don't but I have other laptops that work fine in the same location. Yet two new laptops with windows 8 have very poor reception

probably you can take a wifi card out and install it in the problem one for testing
don't forget to check first what driver you need - then install it
