Simulate Low Network Connectivity for Android

Simulate low network connectivity for Android

You can use emulator for this. Take a look at this page: Android Emulator. Pay attention to next two arguments:

1. -netdelay <delay>

   Set network latency emulation to . Default value is none. See
   the table in Network Delay Emulation for supported values.

2. -netspeed <speed>

   Set network speed emulation to . Default value is full. See
   the table in Network Speed Emulation for supported values.

   Speeds for reference in increasing kbps:

                           UP       DOWN
                     -------- ----------

Simulate slow network on Android simulator

The emulator lets you simulate various network conditions. You can approximate the network speed for different network protocols, or you can specify Full, which transfers data as quickly as your computer allows.

Specifying a network protocol is always slower than Full. You can also specify the voice and data network status, such as roaming. The defaults are set in the AVD.

Select a Network type:

• GSM - Global System for Mobile Communications
• HSCSD - High-Speed Circuit-Switched Data
• GPRS - Generic Packet Radio Service
• EDGE - Enhanced Data rates for GSM Evolution
• UMTS - Universal Mobile Telecommunications System
• HSPDA - High-Speed Downlink Packet Access
• Full (default)

Speeds for reference in increasing kbps:

                        UP       DOWN
                  -------- ----------

evdo  EVDO        75,000.0  280,000.0
full  No limit           ∞          ∞

Select a Voice status, Data status, or both:

• Home (default)
• Roaming
• Searching
• Denied (emergency calls only)
• Unregistered (off)

Simulate Slow Internet Connection on a REAL device?

In one of your comments you mentioned that you have a DD-WRT router, which is really a tiny Linux box. So you may be able to get a way with the tc command:

tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 10mbit 
tc class add dev $DEV parent 1: classid 1:1 cbq rate 512kbit allot 1500 prio 5 bounded isolated 
tc filter add dev $DEV parent 1: protocol ip prio 16 u32 match ip dst 195.96.96.97 flowid 1:1

Simulate low bandwidth in android

I solved the problem by slowing down the network of my PC with network simulator. Then I created a virtual wifi with win 7 and connected my phone with it.

How to limit speed of internet connection on Android emulator?

For Android Studio projects you can do the following:

If you need to change net speed temporarily, then on an emulator toolbar, click three dots (settings), go to Cellular tab and configure the network speed there. You need to have a recent Android Tools.

If you want to set this speed permanently for some emulator image:

1. Open menu Tools -> Android -> AVD Manager
2. Select/create your emulator avd image, click Edit
3. Click Show Advanced Settings button

4. Set the desired net speed

   full  No limit           ∞          ∞
   

5. Re-launch the emulator

OLD ANSWER (obsolete)

If you are working in Eclipse, go to Run->Run Configurations, select your run configuration and then go to "Target" Tab. There you will find a "Network Speed" combobox (under the "Emulator Launch Parameters" section).

If you are running emulator from command line, then you can use "-netspeed" cmd line parameter (run emulator -help-netspeed for overview of possible options)
