# Select Remote Node To view your account information and send transactions, PolkaGate connects to **RPC nodes** — servers that provide blockchain data and accept transactions to be submitted to the network.\ Each blockchain has its own set of RPC nodes, which are distributed globally. When you open the extension, **PolkaGate automatically selects the fastest and most reliable RPC node** to ensure a smooth user experience. However, if you notice latency or delays when fetching data or sending transactions (which is rare), you can **manually switch the RPC node** to one that performs better for your region. To change the RPC node in **extension mode**, open **Settings → Extension Settings → Networks** tab, and select your preferred node.

Select the network whose RPC node you want to change by clicking on its name:

On this page, you can see all the RPC nodes of the selected network (in this example, Polkadot) along with their connection ping. Select your preferred node and then leave the page.\ **Note:** All selected networks are set to *auto mode* by default. In full-screen mode also, open **Settings** (from the left hand side menu) **→ Network Settings** tab, and select your preferred node.

Select the network whose RPC node you want to change by clicking on its name:

On this page, you can see all the RPC nodes of the selected network (in this example, Polkadot) along with their connection ping. Select your preferred node and then click on the **Apply** button. Note that you have the option to make yourself independent of these RPC nodes by using a light client, which is available for some networks at the end of the list of endpoints. However, please be aware that this feature is still experimental. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.polkagate.xyz/polkagate/polkagate-extension-user-guide/select-remote-node.md?ask= ``` The question should be specific, self-contained, and written in natural language.
