Configuration to extend Wi-Fi signal with Access Points

[screenofdeath]

Hello everyone, I need to setup a network to extend the Wi-Fi signal so everyone can connect within any place in the house to access internet. My network diagram is the following:

The description of every equipment involved in the network is the following:

Name: Router-1
Brand: Motorola
Model: SBG901
IP: 192.168.0.1
Subnet mask: 255.255.255.0
Gateway:
DNS1:
DNS2:
SSID: TESTNETWORK
Security type: WPA-PSK
Algorithm: TKIP
Pre-shared key: c6782a9e4c924ab170dc
Wi-fi channel: 1
DHCP: Yes
DHCP Start IP: 192.168.0.10

Name: Switch-1
Brand: TRENDnet
Model: TEG-S81g

Name: AP-1
Brand: TRENDnet
Model: TEW-637AP(A)
IP: 192.168.0.2
Subnet mask: 255.255.255.0
Gateway: 192.168.0.1
DNS1:
DNS2:
SSID: TESTNETWORK
Security type: WPA
Algorithm: TKIP
Pre-shared key: c6782a9e4c924ab170dc
Wi-fi channel: 3
DHCP: N/A
DHCP Start IP: N/A

Name: AP-2
Brand: TRENDnet
Model: TEW-637AP(A)
IP: 192.168.0.3
Subnet mask: 255.255.255.0
Gateway: 192.168.0.1
DNS1:
DNS2:
SSID: TESTNETWORK
Security type: WPA
Algorithm: TKIP
Pre-shared key: c6782a9e4c924ab170dc
Wi-fi channel: 5
DHCP: N/A
DHCP Start IP: N/A

Name: AP-3
Brand: TRENDnet
Model: TEW-637AP(A)
IP: 192.168.0.4
Subnet mask: 255.255.255.0
Gateway: 192.168.0.1
DNS1:
DNS2:
SSID: TESTNETWORK
Security type: WPA
Algorithm: TKIP
Pre-shared key: c6782a9e4c924ab170dc
Wi-fi channel: 7
DHCP: N/A
DHCP Start IP: N/A

Notes: For Router-1, information for Gateway, DNS1 and DNS2 is not available since I forgot to take note of this before leaving the place. For AP-1, AP-2, AP-3, information for DNS1 and DNS2 is not available since it should be the same as Router-1 (if this is wrong, please correct me).

I´ve been doing some research on several methods available to extend Wi-Fi such as WDS (not a standard in industry, requires equipment to be compatible/same brand), Normal configuration (the method I used above) and Repeaters (a method I don't truly understand how it works but seems to be less reliable since it cuts down connection speed half).

The information shown here fits to a normal configuration (couldn´t find a technical name for this method, so I use "normal" instead) where I configure my access points with same SSID and same security type/password, also set different channels to avoid interference between access points and turn off DHCP in all access points to make sure just router delivers IPs to clients.

My questions about this so famous "normal" configuration are the following:

Does this method creates a dead-point when the client switches between equipment? (For example, if I´m downloading a file and I move around my house, will my download fail when switching from 1 access point to another?

How does client selects who to connect in case I´m in a point where 2 signals are available?

Is this method acceptable in wireless networking (personally I find it not so professional from my limited knowledge of wireless networking)?

Would you recommend another method, that could be more professional and reliable based on the equipment available?

Should router and access points be in same Wireless mode? (For example, set all of them to 802.11g mode, or set all of them to 802.11b and g mixed mode; 802.11n is not taken in consideration here since the Router doesn't support that mode)

Thanks for your help and recommendations.

Wireless roaming is not available on a wireless computer network.

[qoute] if I´m downloading a file and I move around my house, will my download fail when switching from 1 access point to another?[/qoute]

yes, since the only way it will switch to another AP is by loosing signal of AP1


[qoute]How does client selects who to connect in case I´m in a point where 2 signals are available? [/qoute]

which ever is higher in the SSID list on your device


[qoute]Is this method acceptable in wireless networking[/qoute]

yes


[qoute]Would you recommend another method, that could be more professional and reliable based on the equipment available?[/qoute]

No.


[qoute]Should router and access points be in same Wireless mode?[/qoute]

No, leave them in the highest mixed mode
